Question

An object of mass 1 kg has a P.E of 1 J relative to the ground when it is at a height of

​

Answer 1

Explanation:

Potential energy is a relative term so taking ground surface as refrence then potential energy is given by mgh.

So 1×9.8×h=1J all are in SI units.

So h=0.102m.

Answer 2

Answer:

potential energy is a relative term so taking ground surface as reference than potential energy is given by MGH

so1×9.8×h=1j all are in SI unit
