Question
If the electric field potential difference between points A and B is equal to 40 volts. Find the work done by an external force in carrying a charge 7µC from A to B at a constant speed. *1 point0.00028 J0.0027 J0.080 J0.0007 J
Solution
The work done by an external force in carrying a charge from one point to another in an electric field is given by the formula:
W = Q * V
where: W is the work done, Q is the charge, and V is the potential difference.
Given: Q = 7µC = 7 * 10^-6 C (since 1µC = 10^-6 C) V = 40 V
Substituting these values into the formula, we get:
W = 7 * 10^-6 C * 40 V = 0.00028 J
So, the work done by an external force in carrying a charge of 7µC from point A to B at a constant speed is 0.00028 J.
