Question

The tail of the comet is due to

Sublimation of water on the comet

Vaporization of water on the comet

Vaporization of heat on the comet

cooling of water in the comet

Open in App

Solution

Verified by Toppr

Correct option is A. Vaporization of water on the comet
If a comet approaches the sun, the substances like water etc. on the comet, get vaporised due to the heat of sun, and radiation pressure forces of these vapours move away from the sun. Hence, it forms the tail of the comet.

Reason
Gravitational force is a non conservative force.
Assertion
Comets move around the sun in elliptical orbits. The gravitational force on the comet due to sun is not normal to the comets velocity but the work done by the gravitational force over every complete orbit of the comet is zero.

Comets move around the sun in highly elliptical orbital. The gravitational force on the comet due to the Sun is not normal to the comets velocity in general. Yet the work done by the gravitational force over every complete orbit of the comet is zero. Why?
