A partical is realeased from the top of two inclined rought surface 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 the block etc) are same in both the cases. Let `K_(1) and K_(2)` be the kinetic energy of the partical at the bottom of the plane in two cases. Then
A. `K_(1)=K_(2)`
B. `K_(1) gt K_(2)`
C. `K_(1) lt K_(2)`
D. Data insufficient
