Pseudo Force: Practice Problem & Solution

A block is kept on the frictionless inclined surface with angle of inclination . The incline is given an acceleration a to keep the block stationary w.r.t incline plane. Then a is equal to Pseudo Force diagram: A block is kept on the frictionless inclined
g/tan α
g cosec α
g
g tan α

Solution Explained:

To solve this problem, we apply the core principles of Pseudo Force. Understanding the underlying formula is key to arriving at the correct answer below:

Taking incline plane as frame of reference,  Pseudo force ma act towards right.

component of Pseudo force up the incline is m.a.cos α which is balanced by m.g.sin α. so,

m.a.cos α = m.g.sin α

⇒a= g tan α
