(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 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 |
, where 
is the radius of earth and 
is the angular velocity of revolution of earth about its polar axis
