The figure shows two point charges 2Q(>0) and -Q. The charges divide the line joining them in three parts I, II, and III.
Which of the following option is correct

A

Region III has a local maxima of electric field.

B

Region I has a local minima of electric field.

C

Equilibrium position for a test cfharge lies in region II.

D

The equilibrium (if there is any) is stable for a negative test charge.

Text Solution

Verified by Experts

The correct Answer is:
A, D
a.,d.
Electric field is zero only at a point in region III. Equilibrium at this point will be stable for a negatie charge.
