Answer:

That's obviously A.

Where the electric field is zero, the force on the charge is,

#vecF =qvecE = 0#

Explanation:

Consider the case of B.

Here, #E = 1/e# where #e# is the electronic charge.

Thus, magnitude of the force would be, #F = q/e# which is never zero, since the electronic charge is not zero.

If the charge is an electron (or a proton) then the absolute value of the force is 1.

Here, #e = 1.6 * 10^(-19) C#
