Answer 1

Perpendicular to the side AB

Explanation:

Given: Four charges are arranged at the corners of a square ABCD, as shown.

Find: The force on +ve charge kept at the center pf the square is.

Solution:

Please see the attached picture for the diagram. We find that the charges at A is -2q, B is +q, C is -q, and D is +2q. Then the force will be a positive charge kept at the center of the square. It will be 2FCosθ and it will be perpendicular to the side AB.
