HW #3 (Sec 19.1-4) Begin Date: 9 16 2016 12:00:00 AM-Due Date: 9 26 201 / 11:59:00 PM End Date: 10/3/2017 11:59:00 PM (14%) Problem 4: A single point charge in vacuum has imaginary equipotential surfaces around it which are spherical due to the symmetry of the situation. Assume we have a charge q 1.5x 10-10 C and such a surface with potential V-31 V > 33% Part (a) Input an expression for the radius of this surface, r, in terms of the given quantities.

Hints remaining Feedback: 0 % deduction per feedback. -An equipotential surface is a surface on which the electric potential has the same value everywhere. Use the formula for the charge and the distance from it due to a point charge in terms of the 33% Part (b) what is the radius, in meters? 33% Part (c) What is the radius, in meters, of a 10,000 V equipotential surface?Explanation / Answer
(a) V=q/4 r
(b)31=9*10^9*1.5*10^-10/r
r=9*10^9*1.5*10^-10/31
=0.0435m
(c)10000=9*10^9*1.5*10^-10/r
r=9*10^9*1.5*10^-10/10000
=1.35*10^-4m
