A man attempts to pick up his suitcase of weight ws by pulling straight up on the handle.(Figure 1) However, he is unable to lif
t the suitcase from the floor. Which statement about the magnitude of the normal force n acting on the suitcase is true during the time that the man pulls upward on the suitcase?
A. The magnitude of the normal force is equal to the magnitude of the weight of the suitcase.B. 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.C. The magnitude of the normal force is equal to the sum of the magnitude of the force of the pull and the magnitude of the suitcase's weight.D. The magnitude of the normal force is greater than the magnitude of the weight of the suitcase

Answer:
Given:
Weight of solid in air,
Weight of solid in water,
Weight of solid in liquid,
Solution:
Calculation of:
1. Relative density of solid,
2. Relative density of liquid,
3. Density of liquid in S.I units:
Also, we know:
where
= density of liquid
= density of water
Now, from the above formula:
