Answer to Question #9654 in Mechanics | Relativity for kapil
agravitational field. If a first body of mass MA is placed at a distance r from a second body of mass MB, each body experiences an attractive force FG whose magnitude is FG =GMAMB/r2, where G is the universal constant of gravitation, equal to 6.67×10−11 N·m2·kg−2. This is sometimes referred to as gravitational mass.[note 1] Repeated experiments since the 17th century have demonstrated that inertial and
gravitational mass are equivalent; since 1915, this observation has been
entailed a priori in the equivalence principle of general relativity.
