this is a jee question does anyone has any idea how this works? · 5 months, 1 week ago

Hey guys which test series will you join apart from fiitjee?

i am preferring allen over resonance what do your guys think? · 5 months, 1 week ago

Log in to reply

If online tests are okay for you, then: assuming you are in FIITJEE, you must be having access to myPAT - did you try them? Besides there is AIiTS, if you want to give tests comparable to JEE Advanced (unlike AITS!).

Besides, there's Embibe. [A note for Embibe: recently, they have started charging Embiums (virtual currency on Embibe that you can either purchase by real-world cash or earn by solving questions on Embibe) for various services on the site.] · 5 months, 1 week ago

Hey Guys i have got a problem . In my CPP This problem doesnt have answer . can you guys solve and tell me the answer i am getting w = 2

A Particle is at the lowest point of a smooth wire frame in the shape of parabola lying in the vertical x-y plane having equation x^2 =5y (x,y are in meter) . after slight displacement particle is set free. find angular frequency of oscillation

take g = 10

Bro! Do you have some good questions which are more easily solved by Energy method than Force method ?

I u have , then share some bro!

And I have got one good q , you may like to solve

This one · 6 months ago

Log in to reply

By Energy Method , Answer is coming 2 .

Let me also try by Force Method . · 6 months ago

Log in to reply

By Force method also , answer is coming 2.

But by Torque method , I dont think the answer will come easily!!! · 6 months ago

Log in to reply

I am also getting 2...same approach · 6 months ago

Log in to reply

I am also getting w as 2.

I used the approximation that for small displacement, tanz=b/a=a/5 where b and a are position coordinates of the particle at some instant and also that for small z,tanz is almost equal to z. · 6 months ago

even i used the same approach · 6 months ago

Hey guyz please help!

A uniform rod of mass m and length l is hinged about a point and is initially horizontal.Now the rod is released and it can rotate freely about an horizontal axis passing through A.

Find the tension in the midpoint of the rod when it becomes vertical.

My answer is not matching , I am getting 17/8 (mg) .I used integration.

Please help.

Thanks. · 6 months ago

Log in to reply

Thus tension at topmost point,the point just below the hinge, comes out to be 3mg/2, but it not physically realisable,what say? · 6 months ago

Log in to reply

those who are getting 17mg/8 would have ignored the weight of half rod while writing equilibrium equations · 6 months ago

Log in to reply

Edit:

I made a mistake, now I am getting 9mg/8 ,it seems to be correct since it is given in the option while rest of the answers, 13mg/8 and 17mg/8 are not in option. · 6 months ago

Log in to reply

$$\dfrac{9mg}{8}$$ is the value excluding the weight of the half rod · 6 months ago

Log in to reply

What is the meaning of "excluding the wt if half rod"? · 6 months ago

Log in to reply

Tension in midpoint of rod = weight of the one half + centripetal force.

centripetal force comes out to be 9mg/8 · 6 months ago

Log in to reply

Centripetal force 9mg/8?? havent you taken into account the hinge reaction? · 6 months ago

Log in to reply

hinge reaction!? · 6 months ago

Log in to reply

Yup there will be some hinge reaction too from the hinge on the rod · 6 months ago

Log in to reply

but what it has to do with tension in mid point ? · 6 months ago

seems like we have solved the problem using different approaches · 6 months ago

In writing equilibrium equation along the rod for the rod have you taken into account the weight of half rod?? · 6 months ago

How to improve chemistry??

I really suck at it and it always pulls my rank down a lot.

We have just started organic chemistry.

Help please! · 6 months, 1 week ago

Log in to reply

and if you keep away FIITJEE AITS Organic chemistry is the most scoring part of chemistry along with inorganic. · 6 months, 1 week ago

Log in to reply

Organic chemistry takes a lot of time and patience to master.

In beginning i also faced this problem but fortunately we were given sufficient time to revise it again and again. in beginning you will forget reagents named reactions will remind you of biology.

Just one advice do GOC Properly . It is the KEY For ORGANIC.

I Had to do it again in march this year coz i didn't studied it properly in 11th . · 6 months, 1 week ago

Thanks, but I am asking about inorganic and physical chemistry, please help. · 6 months, 1 week ago

Inorganic i cant say. i am myself learning it.

3. That density one density is not acceptable (bonus +3)
4. That electfonegativity one (ABC) (+3)

1. Maths that cos[pi/x]cos () one 1 (ABC)(as x tends to zero the cos tends to 0 (second cos) ) (+3)
2. Match f (x) = that sin [] that long one . I got discontinuous at 5 points . (+2)
3. Int 1.that f(x) = X sin (quadratic ) one . I got at 5 points (as it was cont. At -1,0,1,2. (+6)
4. Int 8(that f (x) = xln^2x one. Ans 1 (+6)

Physics

1. That mgcotx and mgtanx one (+3)
2. That ring one (BC) (+3)
3. That particle velocity and acc (Only A) (+3)
4. That int of pulleys ans 16 (bonus +4)
5. Ans omega finding one answer 20. (Bonus +4) .

If I consider these all then my score (at max) can be 221.
