Question

Please help!!

two bodies A and B of equal mass are placed at the height 5m and 7m respectively. which of the body has greater potential energy​

Answer 1

Mass of body A, m

1

=m

Mass of body B, m

2

=m

Height h

1

=h

Height h

2

=2h

Acceleration due to gravity, g

1

=g

Acceleration due to gravity, g

2

=g

PotentialEnergy(P.E

2

)

PotentialEnergy(P.E

1

)

=?

P.E=mgh

⇒P.Eαh

(∴ 'm' and 'g' are constants)

⇒

P.E

2

P.E

1

=

h

2

h

1

⇒

P.E

2

P.E

1

=

2h

h

⇒

P.E

2

P.E

1

=

2

1

Therefore, the ratio of potential energy is of the two bodies is 1 : 2.
