A work of 10 J is done in moving a body through 1 m, in the direction of the applied force. Calculate the magnitude of the applied force.

Open in App

Solution

Step 1: Given data:
Work done is w = 10 J.
Distance moved by the body in the direction of force is d = 1 m.
Step 2: Formula used:
According to the formula,
work done = applied force x distance moved in the direction of force
Applied force = $\frac{work done}{distance moved}$
Where f is the applied force.
Step 3: Calculation:
Finding the magnitude of the force,
f = $\frac{w}{d}$ = $\frac{10 J}{1 m}$ = 10 N
Thus, the magnitude of applied force is 10 N.
