Answer:B
Explanation:
Given
man is unable to lift the suitcase thus
Magnitude of Normal reaction will weight minus magnitude of force pull
From FBD
[tex]N+F=W_s[/tex]
[tex]N=W_s-F[/tex]
Where F=Pull Force
N=Normal reaction

Answer:
The magnitude of the normal force is equal to the magnitude of the weight of the suitcase minus the magnitude of the force of the pull.
