Chapter 5 - Force and Motion - Conceptual Questions: 6

Answer

a) For the same force, acceleration is inversely proportional to mass. Block B has least acceleration, so B has largest mass. b) For the same force, acceleration is inversely proportional to mass. Block C has high acceleration, so C has small mass. c) We know that F = ma . Since F is same for A and B, Ma x 5 = Mb x 3 Ma/Mb = 3/5.
