Question

7 (7 pts). Two charges, q = +120. μC and Q = +259. μC, are initially separated by a distance of 33.5 cm. Q moves to a distance of 115 cm from q, while q is B held in place.

a) Generate an accurate graph of the electric force on Q over the given distances.

b) Graphically determine the work done as Q moves over the given distances.

c) Determine the change in electrical potential energy when Q moves from 33.5 cm to 115 cm

d) Did the potential energy increase, decrease, or remain the same as Q moves from 33.5 cm to 115 cm?

e) If Q has a mass of 12.2 g and an initial velocity of 750. m/s, then what is Q’s velocity when it reaches the 115 cm location?
