The gravitational force of the earth on ...

The gravitational force of the earth on a freely falling ball of mass one kilogram is 9.8 N. The acceleration of the earth towards the ball is

A

` 9.8 ms ^(-2)`

B

negligible.

C

slightly less than `9.8 m s^(-2)`.

D

more than `9.8 m s^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
B
Force = mass ` xx ` acceleration
acceleration ` (a) = (" force ")/("mass ") = (9.8N)/((" mass of earth "))`
The mass of the earth is very high, so its acceleration is negligible.

If the gravitational force of earth suddenly disappears, then

A marble is dropped straight down from a distance h above the floor. Let F_(m) = the magnitude of the gravitational force on the marble due to the Earth, F_(e) = the magnitude of the gravitational force on the Earth due to the marble, a_(m) = the magnitude of the acceleration of the marble toward the Earth, a_(e) = the magnitude of the acceleration of the Earth toward the marble. Which set of conditions is true as the marble falls toward the earth? Neglect any effects of air resistance.

The gravitational force due to the earth also acts on the moon because of which it revolves around the earth. Similar situation exists for the artificial satellites orbiting the earth. The moon and the artificial satellites orbit the earth. The earth attracts them towards itself but unlike the falling apple,they do not fall on the earth, why?
