A test Charge of +1.0x10^-6 C is 40cm from a charged sphere of(adsbygoogle = window.adsbygoogle || []).push({});

3.2x10^-3 C.

a)how much work was required to move it there from a point 1.0x10^2m away from the sphere

b)how many electrons were gained or lost from the test object to create the charge?

Given: q1 = 1.0x10^-6 C q2 = 3.2x10^-3 C

Would i first need to calculate: Fe = k (q1)(q2)/r2 ? and then plug that into W = F (delta D)
