An infinite non conducting sheet has a surface charge density σ = 8.00 pC/m2.
(a) Obtain how much work is done by the electric field due to the sheet if a particle of charge q = +1.60 ×10-19 C is moved from the sheet to a point P at distance d = 3.58 centimeter from the sheet?
J
(b) If the electric potential V is defined to be zero on the sheet, determine what is V at P?
V
