When a single charge q is placed on one corner of a square,the electric field at the center of the square is F/q.If three other equal charges are placed on the other corners,the electric field at the center of the square due to these four equal charges is
A)F/q.
B)4F/q.
C)F/(2q).
D)F/(4q).
E)None of the above choices are correct.
