Fig. shows lines of constant potential in an electric field. Out of the three given points P,Q,R where is electric field intensity maximum and where is it minimum ?

A

maximum at Q and minimum at P

B

maximum at P and minimum at Q

C

maximum at Q and minimum at R

D

maximum at P and minimum at R

Text Solution

Verified by Experts

The correct Answer is:
D
Using the relation, `E = - (dV)/(dr)`, we find that
electric intensity is maximum at P and minimum at R.
