Question

Find value o P.E of an object when it is on ground​

Answer 1

Answer:

PE is not defined only change in PE from one position to the other is defined

if you consider ground to be PE level 0 then the PE on the ground will be 0

BUT you can take any point as PE level 0 so if you take say the point 10 metre above ground as PE level 0 then the PE on the ground will be mgh i.e. -10mg
