Question

True or False?

a. The electric potential energy of an electron increases as it moves parallel to the external electric field.

b.The electric potential V(r) due to a point charge decreases with distance away from the source charge.

c.The total work done to move a charge between two points in an external electric field depends on the electric potentials at those points only.

d. The electric potential on the surface of a charged conductor is different from that at any point inside the same conductor.

e. If the distances between two plates of a parallel plate capacitor is quadrupled, but the radius of the cross sectional area is doubled, then the capacitance of that capcitor must not change.

f. If a dielectric substance is inserted between the two plates of a capacitor, its capacitance decreases.
