# Problem 11-33 Electric potential - Positive

The figure shows two parallel, oppositely charged, plates with a potential difference of $6.0\; V$ between them. The plates are separated by $1.1\; cm.$ If we define the potential of the negative plate to be zero,

(a) what is the potential of the positive plate?
(b) what is the potential half way between the plates?
(c) what is the potential at point $A,$ which is $0.28\; cm$ above the positive plate?

If you imagine a positive charge near the upper (negative) plate where V = 0, will it

(A)  run to the positive plate speeding up and increasing its kinetic energy.

(B)   have to be pushed to the positive plate (work done ON it) increasing its potential energy.
