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.]

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

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.

–
But that information is sufficient bro at least to me as here scores are also displayed and practically 5 students used to get selected from here per exam !!

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.

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.

anubhav didn't come for advanced. I am getting little less than 140 in advanced. Prashant is getting more than 180 in advanced. Better watch out for him next time.

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 .

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

Log in to reply

By Energy Method , Answer is coming 2 .

Let me also try by Force Method .

Log in to reply

By Force method also , answer is coming 2.

But by Torque method , I dont think the answer will come easily!!!

I am also getting 2...same approach

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.

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?

Log in to reply

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

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.

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!

and if you keep away FIITJEE AITS Organic chemistry is the most scoring part of chemistry along with inorganic.

Thanks, but I am asking about inorganic and physical chemistry, please help.

For physical i dont feel there is much problem.

Physical is just like know some formulae and concept and apply them to problems thats all!.

which part of physical are you facing problem?

Answers which i feel are wrong are

Chemistry (graph ones ) should be ABCD

H2O2 One should be bonus density cant be 26.5

OCH3 One about incorrect statements i got ABC To that
