A particle is released from the top of two inclined rough surfaces of height ‘h’ each. The angle of inclination of the two planes are 30° and 60° respectively. All other factors (e.g. coefficient of friction, mass of block etc.) are same in both the cases. Let K1 and K2 be kinetic energies of the particle at the bottom of the plane in two cases. Then
- K1 = K2
- K1 > K2
- K1 < K2
- data insufficient
Answer
(C) K 1 2
