The diver has the least gravitational potential energy

. . . when he has gone as low as he can go, and he is at the bottom.

Gravitational potential energy is directly proportional to the height above something or somewhere.

We have the formula for gravitational potential energy is,

E=-GMm/r

where, G is universal gravitational constant

M is the mass of earth

m is the mass of diver

r is the distance between diver and centre of earth

and negative sign(-) is used because work has to be done against the force of gravity.

At constant GMm, E is inversely proportional to the -r.

So when diver goes lower and lower, value of r decreases and makes the magnitude of E high. But the negative sign converts the value into least.

Therefore, diver has least gravitational potential energy.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
