Two uniform metal spheres with masses of 100kg and 150kg have radii of 6.0 cm and 8.0 cm, respectively. If their surfaces are separated by a distance of 0.86 m, what is the gravitational force of attraction between the spheres?
Homework Answers
Gravitational force between two objects is given by:
F= G*m1*m2/R^2
m1 = 100 kg, m2 = 150 kg
R = distance between centers of both object = r1 + r2 + d
R = 0.06 + 0.08 + 0.86 = 1.00 m
So,
F = 6.67*10^-11*100*150/1.00^2
F = 1.00*10^-6 N

Two spherical conductors of radii 11.0 cm and 15.0 cm are connected by a long thin conducting wire. After reaching a steady state, the spheres have charges q1 and q2, respectively. If the wire is now cut, and the spheres are placed such that the center-to-center distance between them is 28.0 cm, the spheres repel each other with a force of 2.00 N. Remember: The force between charged spheres depends on the center to center distance. (a) What are q1...
