Question

8) Two identical point electric charges (qA = qB = q= +2uC) are placed respectively in A and B along the Oz axis (OA=OB=a=30cm). A third charge (Q=+4uC) is placed at M on the Ox axis at the abscissa OM=X. Determine the resulting force F exerted by (qA , qB ) on the charge Q placed in M. Express the modulus of F as a function of x and show that F(x) passes through a maximum: Fmax, calculate its value.

Determine the resulting F acting on Q in the case where qA = +q and qB = -q.
