In an electric field. electric potential at point A is 40 V and that at point B is 90 V. The work to be done in taking 2 C charge from point A to point B is …………….. .

A

25 J

B

25 J

C

90 J

D

100 J

Text Solution

Verified by Experts

The correct Answer is:
D
`V_B -V_A = W/Q`
`:. W = Q(V_B - V_A)`
`=(2) (90 -40) =100J`
