To understand Newton's law of gravitation and the distinction between inertial and gravitational masses. In this problem, you will practice using Newton's law of gravitation. According to that law, the magnitude of the gravitational force Fgbetween two small particles of masses m1 and m2, separated by a distance r, is given by Fg=G(m1m2/r^2) where G is the universal gravitational constant, whose numerical value (in SI units) is 6.67×10−11(N⋅m^2/kg^2).This formula applies not only to small particles, but also to spherical objects. In fact, the gravitational force between two uniform spheres is the same as if we concentrated all the mass of each sphere at its center. Thus, by modeling the Earth and the Moon as uniform spheres, you can use the particle approximation when calculating the force of gravity between them. A) Two particles are separated by a certain distance. The force of gravitational interaction between them is F0. Now the separation between the particles is tripled. Find the new force of gravitational interaction F1.
