For a charge Q1, the effect of charge Q2 on Q1 will be,

Electronics and Communication Engineering (ECE) : Electromagnetic Field Theory - Quiz(MCQ)

F1 = F2

F1 = -F2

F1 = F2 = 0

F1 and F2 are not equal

Correct Answer : Option (B) : F1 = -F2

Explanation : The force of two charges with respect with each other is given by F1 and F2. Thus F1 + F2 = 0 and F1 = -F2.
