A test charge of +1.0 x 10^-6 C is 40 cm from a charged sphere of 3.2 x 10^-3 C.
a) How much work was required to move it there from a point 1.0 x 10^2 m away from the sphere?
b) How many electrons were gained or lost from the test object.
Relevant equations:
Ee = kq1q2/r
N = q/E
I know how to find b) but for a), I'm not sure if i had to add the two distances together then subtract the charges and divide it by the new distance. anyways, the help would be much appreciated thanks.
