1.	A uniform square plate of mass m and edge a initially at rest startas rotating about one of the edge under the action of a constant torque tau. Then at the end of the 5^(th) sec after start
Answer» angular momentum is EQUAL to `5tau` KINETIC energy is equal to `(75tau^(2))/(ma^(2))` angular momentum is equal to `2.5 TAU` kinetic energy is equal to `(75tau^(2))/(2ma)` Answer :A::D
