A small-sized 155-kg mass is located 1.50 m from a small-sized 275-kg mass, with both masses fixed in place. Where should you place a third small-sized mass so that the net gravitational force on it due to the original two masses is zero?
 
  What will be an ideal response?

Question 2

A very small round ball is located near a large solid sphere of uniform density. The force that the large sphere exerts on the ball
 
  A) is exactly the same as it would be if all the mass of the sphere were concentrated at the center of the sphere.
  B) is approximately the same as it would be if all the mass of the sphere were concentrated at the center of the sphere.
  C) is independent of the mass of the ball.
  D) is independent of the mass of the sphere.
  E) can only be calculated using calculus.
