Find the potential energy of a 50gof mass 10kg standing on a building floor of 10m above the ground level

solution:

here,

mass(m)=10 kg

acceleration due to gravity(g)=50

height(h)=10

we know,

potential energy(p.e)=m*g*h

                                  =10*50*10

                                   =5000

the potential energy is 5000.

a and b sometimes have a positive value
