Question 1

Three boxes are pulled along a horizontal frictionless floor by a constant horizontal pull P. The boxes are connected by very light horizontal strings having tensions T1 and T2 as shown in the figure. Which of the following statements about the tensions is correct? (There could be more than one correct choice.)



T1 + T2 = P
T2 > T1
T2 = P
T1 > T2
T1 = P

Question 2

Two boxes, A and B, are connected by a horizontal string S on a horizontal floor. A very light wire pulls horizontally on box B, as shown in the figure, with a force of 100 N. The reaction force to this pull is



◦ the force that box A exerts on box B.
◦ the pull that box B exerts on string S.
◦ the pull that string S exerts on box A.
◦ the pull that string S exerts on box B.
