If both $Assertion$ and $Reason$ are correct but $Reason$ is not a correct explanation of the $Assertion$.

Vedclass · Answer

(A) The $Assertion$ is correct: Rockets are launched from west to east to take advantage of the Earth's rotational velocity,which helps in achieving orbital velocity with less fuel.The $Reason$ is also correct: The effective acceleration due to gravity $g'$ is given by $g' = g - \omega^2 R \cos^2 \lambda$. At the equator,the latitude $\lambda = 0$,so $\cos \lambda = 1$,making $g' = g - \omega^2 R$,which is the minimum value.However,the $Reason$ does not explain why rockets are launched from west to east. The launch direction is based on the Earth's rotation,not the value of $g$ at the equator. Therefore,both are correct,but the $Reason$ is not the correct explanation for the $Assertion$.

$Assertion$: Space rockets are usually launched in the equatorial line from west to east.
$Reason$: The acceleration due to gravity is minimum at the equator.
