Question - Six charges, three positive and three negative of equal magnitude are to be placed at the vertices of a regular hexagon such that the electric field at O is double the electric field when only one positive charge of same magnitude is placed at R. Which of the following arrangements of charges is possible for P, Q, R, S, T and U respectively

Options:

A . +,-,+,-,-,+

B . +,-,+,-,+,-

C . +,+,-,+,-,-

D . -,+,+,-,+,-

Answer: Option D
:
D
If the charges are arranged according to the option (d), the electric fields due toPandSand due toQandTadd to zero, while due toUandRwill be added up.
