State the universal law of gravitation. Write its
formula. Write the units of gravitational constant G.
Answers
Answer:
Newton’s Law of Universal Gravitation states that every particle attracts every other particle in the universe with a force that is directly proportional to the product of the masses and inversely proportional to the square of the distance between them.
F=GMm/r²
where,
where,F is the gravitational force between bodies
where,F is the gravitational force between bodiesm1 is the mass of one of the objects
where,F is the gravitational force between bodiesm1 is the mass of one of the objectsm2 is the mass of the second object
where,F is the gravitational force between bodiesm1 is the mass of one of the objectsm2 is the mass of the second objectr is the distance between the centres of two objects
where,F is the gravitational force between bodiesm1 is the mass of one of the objectsm2 is the mass of the second objectr is the distance between the centres of two objectsG is the universal gravitational constant.
UNIT OF G= Nm²/kg²
Answer:n symbols, the magnitude of the attractive force F is equal to G (the gravitational constant, a number the size of which depends on the system of units used and which is a universal constant) multiplied by the product of the masses (m1 and m2) and divided by the square of the distance R: F = G(m1m2)/R2.
