Question

A body of mass 0.3 kg is raised to attain a potential energy of 5.88 J. What is its height?

0.5 m

1.0 m

1.5 m

2.0 m

Answer 1

Answer: 2.0 m

Explanation: Potential energy is the energy possessed by a body by virtue of its position.

`{\text {potential energy}}=m* g* h`

where m= mass of body=0.3 kg

g= acceleration due to gravity =
`9.8m/s^2`

h = height of body = ?

`5.88kgm^2s^(-2)=0.3* 9.8* h`
`(1J=1kgm^2s^(-2))`

`h= 2m`
