Two spheres A and B of masses `m_(1)` and `m_(2)` respectively collide. A is at rest initially and B is moving with velocity v along x-axis. After collision, B has a velocity `(v)/(2)` in a direction perpendicular to the original direction. The mass A moves after collision in the direction

A

`theta=tan^(-1) (1//2)` to the x-axis

B

`theta=tan^(-1)(-1//2)` to the x-axis

C

same as that of B

D

opposite to the of B

Text Solution

Verified by Experts

The correct Answer is:
B

Applying the law of conservation of momentum we have
in y-direction, `m_(1) u sin theta=m_(2) v//2`
In x-direction `m_(1) u cos theta=m_(2)v`
