1.	A wheel of radius 0.4 m can rotated freely about its axis as shown in the figure. A string is wrapped over its rim and a mass of 4 kg is hung, An angular acceleration of 8" rad - s"^(-2) is produced in it due to the torque. Then moment inertia of the wheel is (g=10" ms"^(-2))
Answer» `2" KG - m"^(2)` `1" kg - m"^(2)` `1.36" kg - m"^(2)` `8" kg - m"^(2)` Answer :C
