WebQ. Assertion :The magnitude of the electrostatic force of interaction between two point charges is directly proportional to the scalar multiplication of the magnitudes of charges and inversely proportional to the square of the distance between them. Reason: Electrostatic force is analogous to gravitational force. Q. WebGravitation is the universal force of attraction that acts between all matter, big and small. It is the weakest of the fundamental forces in nature. State Newton’s law of universal gravitation.
WebRevision notes for class 9 chapter 10 gravitation is available here. The chapter gravitation is aimed to teach students about gravitational force, the universal law of gravitation, the importance of the universal law of gravitation, free fall, weight, mass, thirst and pressure, and relative density. WebSolution. The acceleration experienced by a body falling from a height towards earth is called acceleration due to gravity. Its SI unit is m s 2. It depends on the mass and the radius of the planet. Hence, the acceleration due to gravity at the surface of a planet depends on the mass and the radius of the planet.
