JEE Main · PhysicsEasy
A force of $F = 10 \text{ N}$ acts on a body and displaces it by $d = 5 \text{ m}$ in the direction of the force. Calculate the work done in Joules.
- A.$2 \text{ J}$
- B.$50 \text{ J}$
- C.$15 \text{ J}$
- D.$5 \text{ J}$
Show correct answer & step-by-step solution
Correct answer: B — $50 \text{ J}$
Solution
The work done is calculated using the formula . Since the force and displacement are in the same direction, , so .
