the ratio of their potential energies.
​

Answer 1

Answer:

2:3

Step-by-step explanation:

Two bodies, A and B of equal mass are kept at heights 20 m and 30 m respectively. Calculate the ratio of their potential energies. = 2 : 3.

Answer 2

Answer:

2:3

Step-by-step explanation:

PE= mgh

For Body A:-

height=20 m

mass=m

g= 9.8 m/s²

For Body B:

height= 30 m

mass=m

g=9.8 m/s²

Ratio of PE of Body A: Body B=

mgh of Body A / mgh of Body B

(m×9.8×20)/(m×9.8×30)

2/3
