In the figure, the direction of the force on charge -q is: Down. To the right. To the left. Up.

The four point charges shown in the diagram below are situated at the corners of a square. The charges Q1 and Q3 are + 2μC; Q2 is -6 μC, and Q is a positive charge.The resultant force on Q is:

q,2q,3q and 4q charges are placed at the four corners A,B,C and D of a square. The field at the centre O of the square has the direction along.

A positive charge is placed in an electric field that points south. What direction is the force on the positive particle?

Three equal charges each +Q, placed at the corners of on equilateral triangle of side 'a' what will be the force on any charge

Consider a square with side a. We put the charges q, -q, 2q, -2q in the corners of this square. Check the relation E=-∇ϕ at the center of the square
