An infinite non-conducting sheet consists of a surface charge density of sigma 5.80 pC/m^2.
i) Determine how much work is done by the electric field due to the sheet if a particle of charge q= +1.60 X 10^-19 C is moved from the sheet to a point P at a distance d = 3.56 cm from the sheet?
ii) When the electric potential V is stated to be zero on the sheet, then what is V at P?
