Question
![3. Each of the following parts involves a comparison of the net electric force exerted on a positive
charge+q in two different cases.
a.
In cases A and B shown at right there are
two positive point charges +Q each a
distance s away from a third positive point
charge +q.
Is the net electric force on the +q charge in
case A greater than, less than, or equal to
the net electric force on the +q charge in
case B? Explain.
b. In case C, two positive point charges +20
are each a distance s away from a third
positive point charge +q. In case D, four
positive point charges +Q are each a
distance s away from a fifth positive point
charge+q. (The angle a shown is the
same in both cases.)
Is the net electric force on the +q charge in
case C greater than, less than, or equal to
the net electric force on the +q charge in
case D? Explain
