Explanation:
We know that Gravitational Potential Energy of an object is given by the equation
#PE_G=mgh#
where#m# is the mass of object,#g=9.81" ms"^-2# is acceleration due to gravity and#h# is height of object.
From the equation we see that
This can also be seen from the figure. Also note that other hill is of lesser height.
