In a certain region, electric field `E` exists along the x - axis which is uniform. Given `AB = 2 sqrt(3) m` and `BC = 4 m`. Points A, B, and C are in `x y` plane.
.
find the potential difference `V_C - V_B` between the points `C and B`.

A

2 E

B

3 E

C

`- E`

D

`-2 E`

Text Solution

Verified by Experts

The correct Answer is:
D
`V_C - V_B = V_F - V_B = - E (B F)`
=`-E (BC) cos 60^(@)`
=`- E 4 xx (1)/(2) = -2 E`
