IF X joule of work must be done to move electric charge to 4C from a place, where potential is -10V to another place. Where potential is 5V, then the value of X….J.

A

30

B

60

C

50

D

100

Text Solution

Verified by Experts

The correct Answer is:
B
Amount of work =`q(V_2-V_1)`
`=4[5-(-10)]=5 times 15`
`=60J=XJ`
`therefore X=60`
