The resistance of a moving coil galvanom...

The resistance of a moving coil galvanometer is `20Omega`. It requires 0.01A current for full scale deflection calculate the value of resistan ce required to convert it into a voltmeter of range 20 volt.

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.
