Work required to move the charge
1. The problem statement, all variables and given/known data
a 2.0 pico C charge is locted at point A on an imaginary spherical surface which is centre on a 4.0 micro C point charge 2.8 cm away . How much work is required to move the 2.0 pico C charge to the following two points?
a) to point B, which is located on the same spherical surface an arc length of 3.0 cm away
b) to point C, which is located radially outward from A on another imaginary spherical surface of radius 4.2 cm.
c)what name could be used to describe these spherical surfaces?
2. Relevant equations
I have no Idea but since the question is looking for work, im assuming this equation must be used
Electric force equation? FQ=K(q1q2/r^2)
