Step 1

a)

The gravitational potential energy is given by

Step 2

Here *G *is the gravitational constant, *M* is the mass of Earth, σ is the mass density *R* is the radius of the Earth and *L *is the length of the cable.

Step 3

b)

As the mass density is uniform, the curve can be semi circular.

The radius of the semi circ...
