In a certain region of space, the electric field is along `+y`-direction and has a magnitude of 400 V/m . What is the potential difference from the coordinate origin to the following points?
`a. x=0,y=20cm, z=0`
b. `x=0, y=-30cm, z=0`
`c. x=0, y=0, z=15cm`

Text Solution

Verified by Experts

The correct Answer is:
C
Procedure is same as work done in the above question. The only difference is electric field is
`E=(400hatj)V//m`
`:.V_B-V_A=-int_A^BE.dr=-400(y_f-y_i)`
