NEET Physics Question - Work Energy and Power

Rankers Physics

Topic: Work Energy and Power

Subtopic: Power

A force F = (iˆ + ˆj + 2kˆ) N is acting on a particle moving with constant velocity v = (iˆ + ˆj + kˆ) m/s. Power delivered by force is

3 Watt

4 Watt

5 Watt

6 Watt

Power is dot product of Force and Velocity

P = F.v

⇒ P= (iˆ + ˆj + 2kˆ). (iˆ + ˆj + kˆ)= 1+1+2= 4 watt
