Hard H. W A negative charge q = - 5.0mu * C is placed at the point B in the electric field of an unknown charge Q placed at point A as shown in the figure. The charge q experiences a 0.08 N force along the line AB from B to A.

How is the gravitational force related to the distance between two objects?
