Question

A very large sheet of insulating material has had an excess of electrons placed on it to yield a surface charge density of -4.00 nC/m2. (a) As the distance from the sheet increases, does the potential increase or decrease? (e) increase O decrease Can you explain why without any calculations? The electric field points in the direction of increasing potential while pointing away from negative charges and towards positive O The electric field points in the direction of increasing potential while pointing towards negative charges and away from positive O The electric field points in the direction of decreasing potential while pointing towards negative charges and away from positive O The electric field points in the direction of decreasing potential while pointing away from negative charges and towards positive charges charges Does the location of your reference point matter? O Yes No (b) What is the shape of the equipotential surfaces? spheres whose centers lie on the sheet O spheres whose centers do not lie on the sheet O planes perpendicular to the sheet planes parallel to the sheet (c) What is the spacing (in m) between surfaces that differ by 7.00 V?

Help with Part C. Please show all your work. I have already tried d=V/E= 7/[(2.9x10^-9)/2(8.85x10^-12)
