Question 11: easy

Assertion (A): Comet tail points away from the sun.

Reason (R): Solar radiation vapourise the volatile materials within the comet.

1. Both (A) \(&\) (R) are true and the (R) is the correct explanation of the (A)

2. Both (A) \(&\) (R) are true but the (R) is not the correct explanation of the (A)

3. (A) is true but (R) is false

4. Both (A) and (R) are false

View Answer

The comet tail always points away from the Sun due to solar wind and radiation pressure pushing on the sublimated material. Solar radiation does vaporize volatile materials, forming the tail, but this vaporization itself doesn't fully explain the direction. Hence, both statements are true, but R is not the correct explanation of A.
