Question

A point charge q moves from point P to point S along the path PQRS in a uniform electric field $E$ pointing parallel to the positive direction of the x-axis. The coordinates of the points P, Q, R and S are (a, b, 0), (2a, 0, 0), (a, -b, 0) and (0, 0, 0) respectively. The work done by the field in the above process is given by the expression

Options:

Answer:

B

Solution:

$W = F \cdot S = qE (\hat{i}) \cdot (- a \hat{i} - b \hat{j}) = - qE a$ . Option (B).

TestHub · Accepted Answer

W = F ⋅ S = qE ( i ^ ) ⋅ ( − a i ^ − b j ^ ​ ) = − qE a . Option (B).
