Problem: A point charge q1= +2.40μC is held stationary at the origin. A second point charge q2= -4.30μC moves from the point x = 0.175 m ,  y = 0 m , to the point x = 0.275 m , y = 0.275 m .How much work is done by the electric force on q2?

FREE Expert Solution

Work done in moving the charge:

W=kq1q2(1r1-1r2)

The initial distance between the two charges is given by:

ri=(0.175-0)2+(0-0)2

ri = 0.175 m
