1. Two particles having charges of 0.570 nC and 20.5 nC are separated by a distance of 1.20 m .

a) At what point along the line connecting the two charges is the net electric field due to the two charges equal to zero?(Express your answer in meters.)

b)Where would the net electric field be zero if one of the charges were negative?(Enter your answer as a distance in meters from the charge initially equal to 0.570 nC .)

c)Is this point between the charges? Yes or No

2. A charged paint is spread in a very thin uniform layer over the surface of a plastic sphere of diameter 19.0 cm , giving it a charge of -13.0 μC .

a) Find the electric field just inside the paint layer. (Express your answer in newtons per coulomb.)

b) Find the electric field just outside the paint layer. (Express your answer in newtons per coulomb.
