Assertion: Three equal charges are situated on a circle of radius `r` such that they form on equilateral triangle, then the electric field intensity at the centre is zero.
Reason: The force on unit positive charge at the centre, due to the three equal charges are represented by three sides of a triangle taken in the same order. Therefore, electric field intensity at centre is zero.

A

if both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B

If both Assertion and Reason are true but Reason is not the correct explanation of the Assertion.

C

if Assertion is true, but the Reason is false.

D

if both Assertion and Reason are false

Text Solution

Verified by Experts

The correct Answer is:
a
Resultant of electric intensity at `O` due to `B` and `C` is equal and opposite to that due to `A`
