1.	Kinetic energy and angular velocity of a rigid body are E and omega respectively. Now angular velocity of the body is increased by 2%. Find out kinetic energy.
Answer» `1.03E` `1.08E` `1.02E` `1.04E` SOLUTION :Rotational kinetic ENERGY `E=(1)/(2)Iomega^(2)` here `omega.=1.02omega` `therefore E.=(1)/(2)I(omega.)^(2)=(1)/(2)I(1.02omega)^(2)` `therefore E.=1.04E`
