A small charge q is placed in the electric field of a large charge Q.
Both charges experience a force F.
What is the electric field strength of the charge Q at the position of the charge q?
A) F/(Qq)
B) F/Q
C) FqQ
D) F/q
Answer is D, why isn't it B? :O HELP

can anyone explain Q11 (b) (i)? I read an explanation somehwere and it said that the two forces have to be subtracted because they are opposite in direction. Why subtract when both forces are in same direction? Shouldn't we add? Both springs will exert a force to the left to bring it to the equilibrium position right?
