The formula for work (W) is W = F × d, where F is the force and d is the displacement in the direction of the force. 1 Joule = 1 Newton × 1 meter. We need to check which option results in W = 1 J. Option A: N·m = 1 J. Option B: F = 2 N, d = 1 m. W = 2 N × 1 m = 2 J. Option C: F = 1 N, d = 1 cm = 0.01 m. W =
Work is said to be one Joule when a force of
