A particle of mass m slides along curved − − flat − − curved track. The curved portions of the track are smooth. If the particle is released at the top of one of the curved portions the particle comes to rest at flat portion of length l and of coefficient of kinetic friction = μ μ kinetic after covering length of
Text Solution
Verified by ExpertsThe correct answer is:
D
use P.E. = Work done
mgH = μ μ kinetic mgS
or S = 
The particle covers the length l or not, or covers it repeatedly is determined by the above relation.
