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.

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

Four point charges qA = 2 mC, qB = –5 mC, qC = 2 mC, and qD = –5mC arelocated at the corners of a square ABCD of side 10 cm. What is theforce on a charge of 1 mC placed at the centre of the square?

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

Three point charges, each equal to +Q, are placed at the vertices of an equilateral triangle. A fou charge q is placed at the centroid such that the system of charges is in equilibrium.
