Question

A boy carries a load of 100 N to a horizontal distance of 100 m. The work done by the load is:

• A. 9800 Nm
• B. 0 Nm
• C. 1 Nm
• D. 1000 Nm

Answer 1

The correct option is B 0 Nm

Here load is acting downward and the displacement is horizontal. Force and displacement are perpendicular to each other, so work done will be $0$.
