Please explain and write clearly:
Two charges are placed near a large, flat, conducting plane such that the line joining the charges strikes the conductor at a right angle. The closer charge is exactly halfway between the conductor and the more distant charge. The charge density at the point on the conductor in line with the two charges is measured to be exactly zero. a. Compute the ratio of the two charges qlz, including the sign (negative if they 4...

Two charged objects are placed near each other, as shown below.
Charge A has 16 times the charge of charge B, but Both are
positive.
a) Would you expect the net electric field produced by the two
charges to cancel to zero at some spot to the left of A, right of
B, or in between the two charges? (not counting infinitely far
away)

Point P
A positive point charge +q is placed at point p to the right of two
charges, A and B. The net force on the +q charge is found to be
zero. Which of the statements below are true?
True False Reversing the sign of +q to -q would make the
force on it nonzero.
True False B must have the same sign as A and be less in
magnitude.
True False The magnitude of the charge A must be smaller
than...
