Question

(a) no force is acting on a test charge placed at point P

(b) Q and q must have the same sign

(c) the electric field must be zero at point P

(d) the net work needed to bring a charge from infinity to point P is zero

Charges Q and q (Q not = to q), separated by a distance d, produce a potential VP = 0 at point P. This means that (a) no force is acting on a test charge placed at point P (b) Q and q must have the same sign (c) the electric field must be zero at point P (d) the net work needed to bring a charge from infinity to point P is zero

Explanation / Answer

Charges Q and q (Q q), separated by a distance d, produce a potential VP = 0 at point P. This means that the net work needed to bring a charge from infinity to point P is zero.
