Physics

Two point charges, A and B. Charge A is located at the originand Charge B is on the x axis at x=40.0 cm.

a) Let the charge of A is +3Q and the charge of B is +Q. Ifcharge B exerts 50.0N on A, find the magnitudes of Q inCoulomb.

b) If A has +2.00 x10^(-6)C and B has -3.00x10^(-6)C, find thepossible locations along the x-axis with zero electricpotential.

c) Let A has +2.00x10(-6)C and B has -3.00x10(-6)C. What isthe electric field E of point P, which is at (x=40.0cm,y=30.0cm)?

d) Let A has +2.00 x10(-6)C and B has -3.00x10(-6)C. How muchwork is needed to move an electron (-1.6 x 10^(-19) C) fromx=50.0cm to x=10.0cm?


Please explain all parts, thanks.
