Q.

If the rotating mass of a rim type flywheel is distributed on another rim type flywheel whose mean radius is half mean radius of the former, then energy stored in the latter at the same speed will be

A. Four times the first one

B. Same as the first one

C. One-fourth of the first one

D. One and half times the first one

Answer & Explanation

Energy stored is directly proportional to square of mean radius.
E1/E2 = (1/2)²/1²
E1/E2 = 1/4

Thus correct option is: C.
