Question

Rockets are launched in eastward direction to take advantage of

• A. the clear sky on the Eastern side
• B. the thinner atmosphere on this side
• C. earth’s rotation
• D. earth’s tilt

Answer 1

The correct option is C

earth’s rotation

The explanation for the correct answer:

In case of option C:

1. Because the earth spins eastward on its axis, if the rocket is launched eastward, it will receive an additional boost from the planet's rotating motion.

The explanation for the incorrect answer:

In case of option A:

1. There is no such reason to launch the rocket in eastern side as clear could be flooded with clouds in a jiffy by a strong wind.

In case of option B:

1. As we know our earth is covered with an envelope of different mixture of gasses in some definite proportion so their is no such thing as thin environment until and unless their is any special case.

In case of option D:

1. The tilted axis of the earth doesn't help the rocket as it gives no extra push the propulsion.

Hence option (C) is the correct answer.
