At each corner of an equilateral triangle identical charges are placed. Then at the centre of the triangle

Three charges each of value q are placed at the corners of an equilateral triangle. A fourth charge Q is placed at the centre of the triangle. If Q = -q :

Three charges, each of value q, are placed at the corners of an equilateral triangle. A fourth charge Q is placed at the centre O of the triangle. (a) If Q = -q , will the charges at corners starts to move towards centre of away from it. (b) For what value of Q at O will the charges remain stationary ?

Three charges each of value q are placed the corers of an equilaterla triangle. A fourth charge Q is placed at the centre of the triangle. If Q = -q, will the charges at the corners move towards the centre or fly away from it?

Three charges, each of value q, are placed at the vartices of an equilateral triangle. A fourth charge Q is placed at the centre of the triangle. (i) If Q=-q , will the charge at the vertices move towards the centre of fly away from it? (ii) For what value of Q will the charges remain stationary?

A,B,C are three points as a circle of radius 1cm .These points form the corners an equilateral triangle .A charge 2C is placed at the centre of circle .The work done in carrying a charge of 0.1muc form A to B is

What is the electric field at the centre of an equilateral triangle, if three identical charges each of charge q are fixed at the three corners of the triangle?
