Question 62012PhysicsJAMB
A rocket is fired from the earth's surface to a distant planet. By newton's law of universal gravitation, the force F will
A
increase as r reduces
B
increase as G varies
C
remains constant
D
increases as r increases
Step-by-Step Explanation
According to Newton's law of universal gravitation, the gravitational force between two masses is inversely proportional to the square of the distance between their centers. As the distance r decreases, the force F increases because the gravitational attraction becomes stronger. This relationship highlights how proximity affects gravitational interactions in space.
