Figure shows a man standing stationary with respect to a horizontal conveyer belt that is accelerating with 1 `ms^(-2)` What is the net force on the man? (Mass of the man = 65 kg)

Options

A. 35N
B. 45N
C. 55N
D. 65N

Answer

D

Explanation

Here , mass of the man , `M=65 kg `
the man being stationary with respect to belt is accelerating forward at the rate of `1 ms^(-2) `( i.e., `a= 1 ms^(-2)`)
the net force F is
` F = Ma = 65 xx 1 =65 N`
