Question

If $1000J$ work is done by a machine to move a body through a distance of $20m$ , then find the force applied to the body.

Answer 1

Step 1: Given data:-

Work done $W=1000J$

Distance travelled $S=20m$

Step 2: Formula used:-

$$\begin{gathered} W=FS \\ \Rightarrow F=\frac{W}{S} \end{gathered}$$

Step 3: To find:-

Force applied $F$,

$$\begin{gathered} \Rightarrow F=\frac{1000}{20} \\ \Rightarrow F=50N \end{gathered}$$

Hence the force applied is $50N$.
