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 an acceleration a towards the right. The relation between a and θ for the block to remain stationary on the wedge is:

Neet pseodo force questions
a= g / (cosec θ)
a = g/(sinθ)
a= g tanθ
a = g cosθ

Solution:

For the block to remain stationary relative to the wedge,

the component of  pseudo force up the incline balances the gravitational component along down the incline:

macos⁡θ=mgsin⁡θma \cos \theta = mg \sin \theta

⇒ a=gtan⁡θ
