Answer 2

The correct relation is, Power = Force × Velocity (option b)

• The general mathematical expression to obtain the magnitude of power is :

$power = \frac{work}{time}$

• Now, the above mentioned mathematical expression can be rewritten in the following way :

As,

work = force × displacement

And,

velocity = displacement/time

So,

power = work/time

power = (force × displacement)/time

power = force × (displacement/time)

power = force × velocity

• So, we can calculate the power from the product of the force and velocity.
• That's why, the correct answer will be option b, (ie. power = force × velocity).
• The rest of the given options do not satisfy the general mathematical expression of calculating the value of power.
