Question

The power (P) is supplied to rotating body having moment of inertia 'I' and angular acceleration 'α'. Its instantaneous angular velocity is ______.

विकल्प

• `"I"/("P"alpha)`

• `"P"/("I"alpha)`

• PIα

• `alpha/("PI")`

Answer 1

The power (P) is supplied to rotating body having moment of inertia 'I' and angular acceleration 'α'. Its instantaneous angular velocity is `underline("P"/("I"alpha))`.

Explanation:

We know P = F × v

= τ × ω        [W = F.S, P = F.V]

= Iα × ω

`therefore omega="P"/("I"alpha)`
