Earth&#8217;s gravitational pull.<\/p>\n<p>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&#8217;s gravity and will never return.<\/p>\n<p>The other options are incorrect because they are not forces that can prevent an object from escaping Earth&#8217;s gravity.<\/p>\n<ul>\n<li>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&#8217;s gravity.<\/li>\n<li>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&#8217;s gravity.<\/li>\n<li>Option D: Moon&#8217;s gravitational pull is a force that acts towards the Moon. It is not a force that can prevent an object from escaping Earth&#8217;s gravity.<\/li>\n<\/ul>\n<p>In conclusion, the escape velocity of a rocket fired from the earth towards the moon is a velocity to get rid of the Earth&#8217;s gravitational pull.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;Centripetal force due to the earth&#8217;s rotation&#8221;
