(a) State Newton’s law of gravity in scalar form and vector
form.
(b) State how potential energy and forces in 1D are related and use
this to determine an expression for the gravitational potential
energy, choosing an appropriate zero-point.
(c) A thin, 1D homogeneous rod of material has a mass M and length
L. The rod is bent into a semi-circle. Determine an expression for
the strength of the gravitational field at the centre of curvature
of the circular arc.

We have been discussing the parallel between Newton’s Universal
Law of Gravity and Coulomb’s force law:
• Both laws define force. Coulomb's
law describes the force between electric charges whereas Newton’s
law describes the force between masses.
• Both are inverse square laws. The
forces are proportional to the inverse square of the distance
between masses for Newton’s law and the inverse square of the
distance between charges for Coulomb’s law.
• The forces defined by both laws are
central...
