The gravitational force of earth is responsible for holding the atmosphere above earth,for rain falling on earth,for flow of water in rivers,keeps us firmly on ground,ball thrown upwards also falls back to earth due to gravity. Download Free solutions of NCERT science Class 9th from SaralStudy. (d) is universal constant of nature Answer: (d) The quantity G is universal constant of nature. Newton's law of universal gravitation states that a particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. Q 1 Page 134 - State the universal law of gravitation. Newton's law of universal gravitation is usually stated as that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. If Ris the radius of the Earth, then according to the universal law of gravitation, the gravitational force (F) acting between the Earth and the object is given by the relation: Please keep a pen and paper ready for rough work but keep your books away. It occurs only when a body is in a state of free fall under the effect of gravity alone. The force that cause acceleration and keeps the body moving along the circular path is acting towards the centre.This is called centripetal force. The force of attraction between the two objects is proportional to the product of their mass and inversely proportional to the square of the distance between them.
