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 the three sides of a triangle taken in the same order. Therefore, electric field intensity at centre is zero.
358187 Two charges each of magnitude \(Q\) are fixed at each of two opposite corners of a square. Two other charges each of magnitude \(q\) are placed at each of the other two corners. If the resultant electric force on \(Q\) is zero, then \(Q\) and \(q\) are related as
