Question

A block of mass m is placed on a smooth inclined wedge ABC of inclination θ as shown in the figure. The wedge is given  acceleration a towards the right. The relation between a and θ for the block to remain stationary on the wedge is

A
a=gcosec θ
B
a=gsin θ
C
a= g cos θ
D
a= g tan θ

Solution

The correct option is B a= g tan θUsing pseudo force, macos θ = mgsin θa = gtan θ
