Question

calculate the potential energy of a body of mass 10 kg at a height of 3 m above the sea level and at a height of 7 m above sea level .g-10m/s*(*:2)

Answer 1

Potential energy =mgh

1. 10kg * 7m *10=10*7*10

=700joule

2.10*10*3= 300joule

Answer 2

▀▄▀▄▀Your answer .. ▀▄▀▄▀

$\bold{Potential \:energy \: of\:the\:object\:at 3m \: height}$

Mass,m=10kg
g=10 m/s²
Height,h=3m

P.E.=mgh
=10*10*3
=300J

$\bold{Potential \:energy \: of\:the\:object\:at 7m \: height}$
P.E=mgh
=10*10*70
=700J
