Question

Hi,

The problem can be seen in the image attachment below.

Thank you for your help!

7. Three charged particles lie on a straight line and are sepa-
rated by a distance d as shown in Fig. 12. Charges q, and q2
are held fixed. Charge q3, which is free to move, is found to
be in equilibrium under the action of the electric forces.
Find q, in terms of q2.
