five joules of work are needed to shift .5 C of charge from one place to another. the potential differences between the places is

To find the potential difference between the two places, you need to use the formula:

Potential difference (V) = Work done (W) / Charge (Q)

In this case, the work done is given as 5 joules (W) and the charge is given as 0.5 coulombs (Q).

Substituting the given values into the formula:

V = W / Q
V = 5 J / 0.5 C
V = 10 volts (V)

Therefore, the potential difference between the two places is 10 volts.
