Question
The power (P) is supplied to rotating body having moment of inertia 'I' and angular acceleration 'α'. Its instantaneous angular velocity is ______.
Options
`"I"/("P"alpha)`
`"P"/("I"alpha)`
PIα
`alpha/("PI")`
MCQ
Fill in the Blanks
Solution
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)`
