A block of mass m is placed on a wedge of mass M. coefficient between then is μ μ <cot θ θ . The wedge is given an acceleration to its left. Find the maximum acceleration at which block appears stationary relative to wedge.
A
B
C
D
None of these
Text Solution
Verified by ExpertsThe correct answer is:
B
N = m (g cos θ θ + a sin θ θ )
ma cos θ θ = mg sin θ θ + μ μ N
ma cos θ θ = mg sin θ θ + μ μ mg cos θ θ + μ μ ma sin θ θ
ma (cos θ θ μ μ sin θ θ ) = mg sin θ θ + mg cos θ θ
or a =
