The work done by a constant force of 5 Newton acting on a body is 5 joules. The Displacement of the body in the direction of the applied force is ______.
1 m
The correct answer is option 2, i.e., 1 m.
The work done (W) by a constant force is given by the formula:
W = F × d × cos(θ)
Since the force and displacement are in the same direction,
θ = 0°, so cos(0°) = 1
Given:
Work done, W = 5 J
Force, F = 5 N
Now,
5 = 5 × d × 1
⇒ d = 1 meter
So, the displacement is 1 m.
If a force ‘F’ acts on a body such that body gets displaced through the distance ‘x’ in the direction of the force, then the work done by the force is ____________.
