(Figure 3.139) shows three circular arcs, each of radius `R` and total charge as indicated. The net electric potential at the center of curvature.
.

A

`Q/(2piepsilon_0R)`

B

`(5Q)/(12piepsilon_0R)`

C

`(3Q)/(32piepsilon_0R)`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
A
Charge can be considered as located at a distance R from the centre. Total charge is (Q – 2Q + 3Q)
Hence `V=1/(4piepsilon_0)(2Q)/R=Q/(2piepsilon_0R)`
