The resistance of a moving coil galvanom...

The resistance of a moving coil galvanometer is `20Omega`. It requires 0.01 A current for full - scale deflection. The value of resistance to convert it into a voltmeter of the range 20 V will be

A

The centre of mass of the system will remain stationary.

B

Mass of block A is equal to mas of block B.

C

The centre of mass of the system will move towards right.

D

It is an impossible physical situation.

Text Solution

Verified by Experts

The correct Answer is:
(BCD)
As net force on system `= 0` (after released)
So centre of mass of the system remains stationary.
