Two spherical asteroids have mases as follows: m1 = 1.0 x 10^20 kg and m2 = 3 x 10^20 kg. The magnitude of the force of attraction between two asteroids is 2.2 x 10^9 N. Calculate the distance between the two asteroids
Gravitational force
In nature, every object is attracted by every other object. This phenomenon is called gravity. The force associated with gravity is called gravitational force. The gravitational force is the weakest force that exists in nature. The gravitational force is always attractive.
Acceleration Due to Gravity
In fundamental physics, gravity or gravitational force is the universal attractive force acting between all the matters that exist or exhibit. It is the weakest known force. Therefore no internal changes in an object occurs due to this force. On the other hand, it has control over the trajectories of bodies in the solar system and in the universe due to its vast scope and universal action. The free fall of objects on Earth and the motions of celestial bodies, according to Newton, are both determined by the same force. It was Newton who put forward that the moon is held by a strong attractive force exerted by the Earth which makes it revolve in a straight line. He was sure that this force is similar to the downward force which Earth exerts on all the objects on it.
1a) Two spherical asteroids have mases as follows: m1 = 1.0 x 10^20 kg and m2 = 3 x 10^20 kg. The magnitude of the force of attraction between two asteroids is 2.2 x 10^9 N. Calculate the distance between the two asteroids
1b) The radius of a typical white dwarf star is a just a little larger than the radius of Earth, but a typical white dwarf has a mass that is similar to the Sun’s mass. Calculate the surface gravitational field strength of a white dwarf with a radius of 7 x 10^6 m and a mass of 1.2 x 10^30 kg. Compare this to the surface gravitational field strength of Earth.
