A block of mass m is placed on a smooth wedge of inclination 
. The whole system is accelerated horizontally so that the block does not slip on the wedge. The force exerted by the wedge on the block has a magnitude.
A
mg
B
mg/cos 
C
mg cos 
D
mg tan 
Text Solution
Verified by ExpertsThe correct answer is:
B
ma cos θ = mg sin θ
a = g tan θ
N = mg cos θ + ma sin θ
= mg cos θ + 
=
