Question

(a) Four identical point charges each with charge +1 µC are assembled to lie on the corners of a square of side

length 1.0 cm. How much work did it take to assemble this charge distribution? I.e., what is the total amount

of work needed to bring in each charge from infinity to the corner of the square? [Hint: It takes no work to bring

in the first charge. But for each successive charge the amount of work needed increases.]

(b) Suppose that you let the fourth charge fly off to infinity. If the point particle has a mass of 10−3 kg, what is

its speed at infinity?
