Find the point where the gravitational force from the Earth is 2 times of that from moon.
Find the point where the gravitational force from the Earth is 2 times of that from moon.
What is the force of gravity at a point Re from the centre of the earth? What is the force of gravity at a point Rm from the centre of the moon? What is Rm at a point on a line between the centres of the Earth and moon that is Re from the centre of the earth?crystal5428 said:I need a help.

The distance between the centres of the Earth and moon is 3.84 x 10^8 m or 3.84 x 10^5 km.crystal5428 said:only the mass of earth, mass of moon and radius of moon and Earth is given.
mass of earth=5.98*10(to the power of 24)
mass of moon=7.35*10(to the power of 22)
radius of Earth and moon=3.84*10(to the power of 8)
The law of universal gravitation states that every object in the universe attracts every other object with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Gravity is the force that pulls objects towards the center of the Earth. This force is what keeps objects on the Earth's surface and also causes objects to fall towards the ground when dropped.
Mass is a measure of the amount of matter in an object, while weight is a measure of the force of gravity acting on an object. Mass is constant, but weight can vary depending on the strength of the gravitational force.
The gravitational constant, denoted by G, is a fundamental constant in physics that determines the strength of the gravitational force between two objects. It is used in the calculation of force of attraction between objects and has a value of 6.674 x 10^-11 Nm^2/kg^2.
Gravity plays a crucial role in the motion of planets and other celestial bodies. The gravitational pull between these objects and the Sun keeps them in orbit, while the gravitational interactions between planets can also affect their orbits.
