Angelina jumps off a stool. As she is falling, the Earth’s gravitational force on her is larger in magnitude than the gravitational force she is exerting on the earth. 1. False 2. This may happen in many cases, but not in every case. 3. True 4. None of these 5. This may happen in a few cases, but it is very rare.

The answer is True. The amount force exerted by any object is directly proportional to its mass. This means that our planet is exerting more gravitational force to Angelina, and Angelina is also exerting a gravitational force on our planet directly proportional to her mass. Angelina is actually falling towards the center of the earth,and also our planet is also moving towards Angelina, but it seems negligible with respect to Angelina.Our Sun is so massive that it held our planet in its orbit because of its gravitational force.

Answer:

1. False

Explanation:

As per law of gravitational attraction force we know that

[tex]F = \frac{Gm_1m_2}{r^2}[/tex]

where we know that

[tex]m_1,m_2[/tex] = masses of two point mass

[tex]r [/tex] = distance between two masses

so here we know that as the force does not depend on individual mass but it will depend on the product of two masses

so here the gravitational force is same in magnitude on both the bodies

so when Angelina jumps off the stool the gravitational force on Earth and on Angelina must be of same magnitude
