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.

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.

@Harsh Shrivastava
–
Thus tension at topmost point,the point just below the hinge, comes out to be 3mg/2, but it not physically realisable,what say?

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

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.

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 .
