Question

Body A of mass Mis dropped from a height of 1
m and body B of mass 3 M is dropped from a
height of 9 m. Ratio of time taken by the bodies
1 and 2 to reach the ground is (g = 10 m/s').​

Answer 1

Answer:

1:27

Explanation:

Both are cases of potential energy.

In case 1,

Mass = 1 m

g = 10m/s^2

h = 1 meter

Potential energy = mgh

= 1 X 10 X 1 J

Similarly, in case 2,

potential energy = 3 X 10 X 9

do case 1 upon case 2 i.e. case1/case 2, and you will get 1/27 i.e. 1:27

you will get your answer
