Question

Fig. shows comets without their tail. Show the tails of the comets at position A, B, and C. In which position will the tail be longest?

Answer 1

The tail of the comet is always directed away from the Sun.


Comets develop tails as they approach perihelion—the place in their orbits when they are closest to the Sun.
The tail will be longest at position B as tail will be longer when it is closer to the sun.
