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 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 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?

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?

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

Three charges each of magnitude q are placed at the corners of an equilateral triangle, the electrostatic force on the charge place at the centre is (each side of triangle is L )

Three charges, q each, are placed at the vertices of an equilateral triangle. What will be the resultant force on charges Q placed at the centroid of the triangle?
