A point charge 4.40 μC is held fixed at the origin. A second point charge 1.20 μC with mass of 2.80×10−4 kg is placed on the x axis, 0.240 mfrom the origin.

a)What is the electric potential energy U of the pair of charges? (Take U to be zero when the charges have infinite separation.)

b)The second point charge is released from rest. What is its speed when its distance from the origin is 0.600 m .

c)What is its speed when its distance from the origin is 6.00 m .

d)What is its speed when its distance from the origin is 60.0 m .
