Chapter 19.1, Problem 3cTH

In case E a positive point charge with +Q is a distance s away from a third positive point charge +q. In case F ten positive point charges, each with charge +Q/10, lie along an arc of radius s centered on a positive point charge +q.

Is the net electric force on the +q charge in case E greater than, less than, or equal to the net electric force on the +q charge incase F? Explain.
