Question

Go to the Physics Exploration Center. Enter through the resource room 311/312 Thaw Hall. Before you start the exploration, answer the following questions: In the arrangement shown below, the two masses are connected to each other via a string. If the horizontal surface (on which mass m2 is sitting) is frictionless, which of the following statements is true: Mass m1 must necessarily be smaller than mass m2 for there to be an acceleration of the masses. Mass m1 must necessarily be larger than mass m2 for there to be an acceleration of the masses. Mass m1 must necessarily be equal to mass m2 for there to be an acceleration of the masses. Mass m1 must be larger than a certain critical mass but not necessarily larger than mass m2 for there to be an acceleration of the masses. Even for the smallest value of mass m1, there will be an acceleration of the masses. A student remarks: "In the setup above, if m1 m2 they will both accelerate." Do you agree with the student? If not, how would you convince him/her otherwise? In the setup above, if the masses accelerate, will the acceleration be constant in magnitude till mass m1 hits the ground? Justify your answer.

Explanation / Answer

1)d 2) m1m2 it is not necessarily grer in mass to produce acc ,small m1 can 3)ac will be constant in magnitude because only g is applied on it it has constant value of 9.8
