A point charge 4.20 μC is held fixed at the origin. A second point charge 1.40 μC with mass of 2.80×10−4 kg is placed on the x axis, 0.260 m from the origin.

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

Part B: The second point charge is released from rest. What is its speed when its distance from the origin is 0.600 mm?

Part C: What is its speed when its distance from the origin is 6.00 mm?

Part D: What is its speed when its distance from the origin is 60.0 mm?

Expert Solution

Use conservation of energy principle where initial potential energy at initial separation is equal to final sum of potential plus kinetic energy as shown below
