plrase answer both

9.1ptl In the Figure, a block m1 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 Call the 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) m1 m2 A) The tension T2 is larger than m2 g B) If the table was completely frictionless, the system as shown could still be in equilibrum C) The net force on the knot is downwards. D) The force of static friction on ml equals T1 E) T3 is equal in magnitude to T1

Explanation / Answer

Since it is in equilibrium

m2g = T2

A is false

is table is friction less then T1 is zero ..it wont be in equilibrium

B is false

It is in equilibrium so net force is zero

C is false

D - True

E - false

And FFFTF

T2 = m2*g

T1 = .21*865 = 181.65

using law of sines

T1/sin(90+theta) = T2 / sin(180-theta) = T3/sin(90)

T2 = 109.58

maximum weigh of block m2 = 109.58 N or 11.17 kg
