Equal torques act on the disc A and B of...

Equal torques act on the disc A and B of the pervious problem, initially both being at rest. At a later instant, the linear speeds of a point on the rim of A and another point on the rim of B are `v_(A)` and `v_(B)` respectively. We have

A

`v_(A) gt v_(B)`

B

`v_(A)=v_(B)`

C

`v_(A) lt v_(B)`

D

the rotation depends on the actual magnitude of the torques.

Two particles A and B of mass m_(A) and m_(B) respectively and having the same charge are moving in a plane. A uniform magnetic field exists perpendicular to this plane. The speeds of the particles are v_(A) and v_(B) respectively, and the trajectories are as shown in the figure. Then

In the following figures (a) and (b), all the surfaces are smooth, string is massless and pulley is ideal. The mass of the rope is 'm' in both the cases (assume both the systems start from rest) If T_1 and T_2 be the tensions at the mid-points of the ropes in fig(a) and fig(b) respectively, then T_1: T_2 is
