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.
