A disc is rotating with angular velocity w. A force F acts at a point ...
Explanation:


Angular Velocity:

Angular velocity is defined as the rate of change of angular displacement with respect to time. It is represented by the symbol ‘ω’.

Force:

Force is defined as any influence that causes an object to undergo a change in motion. It is represented by the symbol ‘F’.

Torque:

Torque is defined as the product of force and the perpendicular distance from the point of application of force to the axis of rotation. It is represented by the symbol ‘τ’.

Power:

Power is defined as the rate at which work is done or energy is transferred. It is represented by the symbol ‘P’.

Calculation of Power:

The power associated with the torque due to the force is given by the formula:

P = τω

where,

τ = r × F (cross product of position vector and force vector)
ω = angular velocity

Substituting the value of τ in the above equation, we get:

P = (r × F)ω

Therefore, the correct option is (1) (r × F).w.

A disc is rotating with angular velocity w. A force F acts at a point ...
Power = torque × omega , torque = Fr sin(a)= F×r so power = (F×r)w
