1.	If the diameter of fly wheel is increases by 1%, then increase in its M.I. about an axis passing through centre and perpendicular to the plane will beA. `1 %`B. `0.5 %`C. `2 %`D. `4 %`
Answer» Correct Answer - C `I=MR^(2)` Differentiating we get, `(dI)/(I)= 0+2 (dR)/(R )` `therefore (dI)/(I)xx 100 = 2((dR)/(R ))xx100` `= 2xx1% xx 100 = 2%`
