Which of the following statements concerning F (A on B), the force that Block A exerts on Block B, is true?
F (A on B) < Mass of A*g
F (A on B) = Mass of A*g
F (A on B) > Mass of A*g
What is the value of F (B on A), the force that Block B exerts on Block A,
F (B on A) = Mass of A*g
F (B on A) = Mass of A*a
F (B on A) = Mass of A*(a+g)
F (B on A) = Mass of B*a
F (B on A) = Mass of B*(a+g)
