Pseudo Force: Practice Problem & Solution

A man of weight W = Mg is standing on a lift which is moving upward with an acceleration a. If g is the acceleration due to gravity, the apparent weight of the man is
W (1 + a/g)
W (1 - a/g)
W
W(a+g)

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 lift as frame of reference, T = mg +ma = mg (1 +a/g) = W (1+ a/g)
