Portion AB of the wedge shown in figure is rough and BC is smooth. A solid cylinder rolls without slipping from A to B. If AB = BC, then let m and n is the ratio of translational kinetic energy to rotational kinetic energy when cylinder reaches point B and C respectively, then –
A
m = 2
B
m = 
C
n = 1
D
n = 5
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(a, d)
K = β K T or K T + K R = β K T ⇒ K T = 2K T
At point B : K T
K R = mgh
⇒ K R = 
At point C : K T + 
= mg × 2h
K T =
