A very dense 1500-kg point mass (
 
  A) and a dense 1200-kg point mass (B) are held in place 1.00 m apart on a frictionless table. A third point mass is placed between the other two at a point that is 20.0 cm from B along the line connecting A and B. When the third mass is suddenly released, find the magnitude and direction (toward A or toward B) of its initial acceleration. (G = 6.67  10-11 N  m2/kg2 )

Question 2

Two equal-magnitude forces are exerted to a door at the doorknob. The first force is exerted perpendicular to the door, and the second force is exerted at 30 to the plane of the door. Which force exerts the greater torque about the door hinge?
 
  A) the first force (exerted perpendicular to the door)
  B) the second force (exerted at an angle)
  C) Both forces exert equal non-zero torques.
  D) Both forces exert zero torque.
