At one point in space, the electric potential energy of a 15 nc charge is 42 μj . part a) what is the electric potential at this point?
express your answer to two significant figures and include the appropriate units.
part b) if a 20 nc charge were placed at this point, what would its electric potential energy be?
express your answer to two significant figures and include the appropriate units.

Part A:

Part B:

Explanation:

Part A:

The potential energy at a point due to a charge is defined as

.

where,

V = electric potential at that point.

Therefore,

Part B:

Now, if the charge at that point is replaced with , then the electric potential energy at that point is given by

the body's situation won't change the forces are equal opposit and on the same body

the answer is a. the yacht traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.
