Heres the problem:(adsbygoogle = window.adsbygoogle || []).push({});

An infinite nonconducting sheet has a surface charge density of 5.80 pC/m^2. How much work is done by the electric field due to the sheet if a particle of charge q = 1.60x10^-19 C is moved from the sheet to a point P at distance d = 3.56 cm from the sheet? Also if the electric potential V is defined to be zero on the sheet what is V at P.

Ok so heres what i tried doing:

using the equations E = density / 2(8.85E-12) to find E

using E i tried finding Volts using the equation V = EdsCos

after that i used V to solve for Work using the equation

V = -w/q

got nothing close to the answer

as reference the answers in the back of the book say

a) 1.87E-21 J

b)-11.7mV

I dont know what im doing please help
