A solid sphere has a uniformly distributed mass of 1.0 xx 10^4 g and a radius of 1.0 m. What is the magnitude of the gravitational force due to the sphere on a particle of mass m = 2.0 kg when the particle is located at a distance of (a) 1.5 m and (b) 0.50 m from the center of the sphere? (c) Write a general expression for the magnitude of the gravitational force on the particle at a distance r le 1.0 , from the center of the sphere. |
