Explanation / Answer

Ans:-

b.False, there is only force of gravity i.e mg so masses are different so forces also different

c.True weight is depending upon mass and acceleration due to gravity and it changes

d.False weight is force ,mass is not. weight varies with gravity but mass is constant

e.True the net force is not be upward

Wapp =normal forceand acceleration is greater
