1just place the charges at different positions (according to the option given)...and check the ELECTROSTATIC INTENSITY(direction and magnitude).
Six charges 3 positive charges 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 is possible for P,Q,R,S,T and U respectively
( O is the centre of the hexagon)
a)+,-,+,-,-,+
b)+,-,+,-,+,-
c)+,+,-,+,-,-
d)-,+,+,-,+,-
Plz tell how you got the answer....
