Consider two circular parallel plates of radius R separated by a
distance d (( R. Assume that these plates have uniformly distributed
surface charges of Q and -Q. Electric field vectors in the region
between the plates will all point perpendicular to the plates from the
positive plate to the negative plate and will have a magnitude of 4(k(
Use equation d(=dVe/d=-qE-dr/q= d(=-E(dr
And the information just given to evaluate the potential difference
between the plates in terms of Q, R, and d.
Argue that you get the same results using the formula for the potential
of an infinite plate :

Consider two circular parallel plates of radius R separated by a distance d R. Assume that these plates have uniformly distributed surface charges of Q and -Q. Electric field vectors in the region between the plates will all point perpendicular to the plates from the positive plate to the negative plate and will have a magnitude of 4k (see attachment)
