A wooden block performs SHM on a frictionless surface with frequency `v_(0)`. The block carries a charge `+Q` on its surface. If now a uniform electric field E is switched on as shown, then SHM of the block will be

A

of the same frequency and with shifted mean position

B

of the same frequency and with the same mean position

C

of changed frequency and with shifted mean position

D

of changed frequency and with the same mean position

Text Solution

Verified by Experts

The frequency will be the same `v=sqrt(k//m)//2pi`. Frequency is independent of any external constant. But due to the constant foce `q//E` toward right, the equilibrium position gets shifted by `qE//K` in forward direction.

A block of mass M has a circular cut with a frictionless surface as shown. The block rests on the horizontal frictionless surface of a fixed table. Initially the right edge of the block is at x = 0, in a co-ordinate system fixed to the table. A point mass m is released from rest at the topmost point of the path as shown and it slides down. When the mass loses contact with the block, its position is x and the velocity is v. At that instant, which of the following options is/are correct?
