Escape velocity of a rocket fired from the earth towards the moon is a velocity to get rid of the

The correct answer is: B. Earth’s gravitational pull.

Escape velocity is the minimum speed required for an object to escape the gravitational pull of a massive body. For Earth, the escape velocity is about 11.2 km/s. This means that if a rocket is launched from Earth with a speed of at least 11.2 km/s, it will escape Earth’s gravity and will never return.

The other options are incorrect because they are not forces that can prevent an object from escaping Earth’s gravity.

• Option A: Centripetal force is a force that acts towards the center of a circle. It is not a force that can prevent an object from escaping Earth’s gravity.
• Option C: Pressure of the atmosphere is a force that acts perpendicular to the surface of Earth. It is not a force that can prevent an object from escaping Earth’s gravity.
• Option D: Moon’s gravitational pull is a force that acts towards the Moon. It is not a force that can prevent an object from escaping Earth’s gravity.

In conclusion, the escape velocity of a rocket fired from the earth towards the moon is a velocity to get rid of the Earth’s gravitational pull.
