You want to put an electron somewhere between the plates of aparallel plate-capacitor so that it will have the maximumelectrical potential energy relative to one of the plates. The bestplace to put it is at the inner surface of the negativeplate.

Explanation / Answer
Potential energy of electron would be givenby U = (1/40)* q * e / r q = chargeon plate. for maximum potential energy, U must bepositive and r should be minimum. since e is - ve , U will assume + ve valueif q is negative, hence electron should be close to - veplate. minimum value of r could be 0, i.e. electronshould be placed on surface of - ve plate.
