If the temperature of a uniform rod is slightly increased by `Deltat`, its moment of inertia I about a line parallel to itself will increased by

A

zero

B

`alphaIDeltat`

C

`2alphaIDeltat`

D

`3alphaIDeltat`

Text Solution

Verified by Experts

The correct Answer is:
A
`I_(1-1)=0+Md^(2)`
Due to change in temperature, no effect on `M` and `d` , hence, `M.I` . Remains same.
