Two point charges `+4q` and `+q` are placed at a distance `L` apart. `A` third charge `Q` is so placed that all the three charges are in equilibrium. Then location. And magnitude of the third charge will be

Options

A. At a distance `(L)/(3)` from `+4q` charge, `(4q)/(9)`
B. At a distance `(L)/(3)` from +4q charge, `-(4q)/(9)`
C. At a distance `(2L)/(3)` from +4q charge, `-(4q)/(9)`
D. At a distance `(2L)/(3)` from +q charge, `(4q)/(9)`

Answer

C
