Question

The force required to do $10J$ of work on a body to displace it by $10m$ is .

• A. 1 N
• B. 10 N
• C. 5 N
• D. 15 N

Answer 1

The correct option is A 1 N

Given,
Work done $W=10J$
Displacement $s=10m$.
Let the force applied be $F$.
We know, $W=F\times s$
So, $F=\frac{W}{S}=\frac{10}{10}=1N$.
Therefore, the force required is $1N$.
