Question

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 B.
True False  If A is negative, B must be positive.
True False  Either A or B must be positive.

Answer 1

the last statement is also true. Because any of the a and b may be positive.
