State Newton's law of gravitation.

Text Solution

Verified by Experts

Newton.s law of gravitation: Every particle in the universe attracts every other particle with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them and the direction of the force is along the line joining the masses.
`F=G(m_1m_2)/r^2`
Where F=force of attraction
`m_1` and `m_2` are the masses of the two particles
r=distance between the particles
G=Universal gravitational constant

Statement I: The force of gravitation between a sphere and a rod of mass M_(2) is =(GM_(1)M_(2))//r . Statement II: Newton's law of gravitation holds correct for point masses.

According to Newton's law of gravitation each particle attracts every other particle. But we do not see bodies on the surface of the earth moving towards each other. Why?

Kepler's third law states that square of period revolution (T) of a planet around the sun is proportional to third power of average distance i between sun and planet i.e. T^(2)=Kr^(3) here K is constant if the mass of sun and planet are M and m respectively then as per Newton's law of gravitational the force of alteaction between them is F=(GMm)/(r^(2)) , here G is gravitational constant. The relation between G and K is described as

Assertion : The centres of two cubes of masses m_(1) and m_(2) are separated by a distance r. The gravitational force between these two cubes will be (Gm_(1)m_(2))/(r^(2)) Reason : According to Newton's law of gravitation, gravitational force between two point masses m_(1) and m_(2) separated by a distance r is (Gm_(1)m_(2))/(r^(2)) .
