Question
In the Figure, a block my sits on a table. There is static friction between block and table. Block m2 hangs from a knot, as shown. Call the tension in the rope connecting the knot to m, "TI. Call the 9.(1pt] tension in the rope connecting the knot to m2, "T2". Call the tension in the third rope (the one tipped up by an angle theta, connecting the knot to the wall), "T3". The system is in equilibrium Which of the following statements are true? (If A and E are true, and the others are not, enter TFFFT) m2 A) The tension T2 is larger than m2 g B) The force of static friction on ml is less than T C) T3 is equal in magnitude to T2 the table was completely frictionless, the system as shown could not be in equilibrum E) The net force on the knot is upwards. Answe TSubmit All Answers Last Answer: FITTF Incorrect, tries 4/6.! 10.[lpt] In the previous problem, bloc block m will remain at rest. k mj weighs 756 N. The coefficient of static friction between the block and the table is 0.27 and the angle theta is 29.20. Find the maximum weight of block m2 for which
Explanation / Answer
FFFTF
A) False, because T2 =m2g
B) False, T1 = friction
C) False, T3 sin theta = T2
D) True, net force on m1 will be non zero in that case.
E) False, net force is zero
