B

If both the assertion and reason are true but the reason is not true the correct explantion of the assertion.

C

If the assertion is true but reason false

D

If both the assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
B
We know that earth revolves from west to east about its polar axis. Therefore, all the particles on the earth have velocity from west to east. This velocity is maximum in the equatorial line, as `v=Romega`, where `R` is the radius of earth and `omega` is the angular velocity of revolution of earth about is polar axis. When a rocket is launched from west to east in equatorial plane, the maximum linear velocity is added to the launching velocity of the rocket, due to which launching becomes easier.
