It is due to earth's gravitational field .
it is the min. velocity required for an object atbearth's surface so that it just escapes the earth's gravitational field.
- Escape velocity at earth surface=11.2km/sec.

Escape velocity of a rocket fired from the earth towards the moon is a...
Explanation:
The escape velocity is defined as the minimum velocity required by an object to escape from the gravitational pull of a celestial body such as a planet or a moon. In this case, the rocket is fired from the Earth towards the Moon, so the escape velocity required is to get rid of the Earth's gravitational pull.
Reasoning:
When a rocket is launched from the Earth's surface, it is subject to the Earth's gravity, which pulls it towards the center of the Earth. In order to overcome this gravitational force, the rocket needs to attain a certain velocity, known as the escape velocity. This velocity is calculated by taking into account the mass of the Earth and the distance between the rocket and the Earth's center.
Options:
a) Earth's gravitational pull - This is the correct answer as explained above.
b) Moon's gravitational pull - This option is incorrect as the rocket is not launched towards the Moon's surface, but rather from the Earth's surface towards the Moon.
c) Centripetal force due to the Earth's rotation - This option is incorrect as the centripetal force due to the Earth's rotation is not significant enough to affect the rocket's escape velocity.
d) Pressure of the atmosphere - This option is incorrect as the rocket is launched from the Earth's surface, and once it reaches a certain altitude, it escapes the atmosphere and is no longer affected by atmospheric pressure.
Conclusion:
The correct answer to the question is option 'A', i.e., 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.
