Q1. If any object is thrown upwards from the Earth with a velocity greater than 11.2 km/s, then the object will:
A Go into space Correct
B Revolve around the Earth
C Return to the Earth
D Revolve around the Moon
Explanation
The escape velocity from the Earth is about 11.2 km/s. If an object is projected upward with a speed greater than this value, it can overcome the Earth's gravitational pull and move into space, assuming air resistance and other losses are ignored. Revolving around the Earth would require a suitable horizontal orbital velocity, not simply an upward throw. Returning to the Earth happens when the speed is below escape velocity. Revolving around the Moon would need capture by the Moon's gravity, which is not implied by this condition.
