Question 1 of 60

Time left: 00:00

A small test charge \(+q\) is moved between two points \(A\) and \(B\) in an electric field. The work done by the electric field in moving the charge from \(A\) to \(B\) is \(+6.0\times 10^{-3}\,\text{J}\). What is the potential difference \(V_A - V_B\)?

Select one option.

\( +\dfrac{6.0\times10^{-3}}{q}\,\text{V} \)
\( -\dfrac{6.0\times10^{-3}}{q}\,\text{V} \)
\( +6.0\times10^{-3}q\,\text{V} \)
\( -6.0\times10^{-3}q\,\text{V} \)
\( 0\,\text{V} \)
