50 x 10 9 C point charge is placed 6.00 m from an identical 2.50 x 10 9 C point charge. How much energy would be required to move a 0.

A 2.50 x 109 C point charge is placed 6.00 m from an identical 2.50 x 109 C point charge. How much energy would be required to move a 0.180 C test charge from a point midway between them to a point 1.00 m closer to either of the charges? (b) After being moved closer to one of the charges, if the test charge is released from rest (other charges stay fixed in position), what will be its speed when it reaches the midway point? The mass of the test charge is 1.55 kg.
