Question

The weight of a person on the earth is 96kg. His
weight in a parachute moving vertically down
wards with an acceleration 0.25g, will be :
(a) 24 kg
(b) 48 kg
(C) 72 kg
(d) 96 kg

​

Answer 1

Answer:

d )96 kg

Explanation:

Because there will be no difference

Answer 2

Answer: (c) 72 kg

Explanation:

When a person is at some height or falling downward with an accelartion then the force on the person equal

F =mg - ma

F =m(g -a )

On putting the values we get F = 96 (10 - 0.25)

= 720 N

As we know F =mg on ground

720 = m ×10

M=72 kg

Please note that ..96kg in ques is mass of the person and g is 10 m/s^(-2) in the solution

Thank you !!
