Class : Class 9
due to radiation pressure
Ans 2:
Class : Class 6
(D) Radiation Pressure
As a comet approaches the inner solar system, solar radiation causes the volatile materials in the comet to vapourize and stream out of nucleus, carrying away dust. the streams of dust and gas thus released form a tail. and since the radiation are towards the comet from one direction and the tail could not repel the radiation, and pointing away from the sun due to the radiation.
