A, B, C, D, P, and Q are points in a uniform electric field. The potentials at these points are `V(A) = 2 V. V(P) = V( B) = V(D) = 5 V`, and `V(C) = 8 V`. Find the electric field at P.
.

A

` 10 Vm^(-1)` along `PQ`

B

` 15 sqrt 2Vm^(-1`) along `PA`

C

`5Vm^(-1)` alone `PC`

D

`5 Vm^(-1)` along `PA`

Text Solution

Verified by Experts

The correct Answer is:
B
` V_c - V_A = E xx 0 . 2 sqrt 2`
` 6 = E xx 0. 2 sqrt 2`
` E = (30)/(sqrt 2)`

` E = 15 sqrt 2 V//m` along pA
