Gravitation is one of the four … Gravitational Constant. What is the gravitational force on it due to the earth at a height equal to half the radius of the earth? Gravity is a force which has an infinite range. Newtonwas the first scientist who studied the force of gravitation. How does the Centre of gravity affect the balance? Plot No. . . m1: The mass of one massive body measured in kgm2: The mass of another massive body measured in kgr2: The separation between them measured in kilometres (Km). NCERT Nots For Physics Class 11 Chapter 8 :- GRAVITATION Every object in the universe attracts every other object with a force which is called the force of gravitation. IndrajeetSingh Sangtani. Acceleration due to gravity at height h from the Earth’s surface is given by the relation:g‘ = g / [1 + ( h / Re) ]2, Where,g = Acceleration due to gravity on the Earth’s surfaceRe = Radius of the EarthFor h = Re / 2g‘ = g / [(1 + (Re / 2Re) ]2= g / [1 + (1/2) ]2  =  (4/9)gWeight of a body of mass m at height h is given as:W‘ = mg= m × (4/9)g  =  (4/9)mg= (4/9)W. Thus, we hope that through these class 11 Gravitation notes, you are now familiar with the basic concepts related to this topic. This force is directly proportional to the product of their masses.
