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 inergia 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
