Question

As shown above, two particles, each of charge +Q, are fixed at opposite corners of a square that lies in the plane of the page. A positive test charge +q is placed at a third corner. What is the direction of the force on the test charge due to the two other charges?

Answer 1

The correct option is: (E)

Explanation:

The force vectors from the two +Q charges point down and to the left (away from the charges) so the resultant force points down and left.
