Pulley Makeup rner Notes.Emate-Foedbad Two masses mi and mz are connected by a massless string which runs over a massless fricbionless puley The tabie h string is always tight (there is never any siack). The masses are free to move f they should. how does the tension acting on m compare The and you may assume that the onms compare with the ht of my? mi m2 Are the masses accelerating? HINT: Think about the forces acting on m No, they stay sttl so they do not accelerate. Cannot determine uniess we know if mi is greater than, less than, or equal to ma- No, they move with a constant velocity so they do not accelerate O Yes, m2 accelerates downward and m accelerates to the right Submit Answer Tries 0/1 How does the tension acting on m2 compare with the weight of m2? HINT: Newton's 2nd Law Cannot determine unless we know if m is grester than, less than, or equai to m Submit Answer Tries 0/1 How does the magnitude of the tension acting on m1 compare with the magnitude of the tension acting on m2 The tensions aging on the masses are equal in magnitude. Impossible to tell unless we know if my is greater than, less than, or equal to m2 The tension acting on mi is larger than the tension acting on m2- The tension acting on m2 is larger than the tension acting on m Submit Answer Tries 0/1 How does the magnitude of the tension acting on mi compare with the weight of ma Cannot determine unless we know if ms is greater than, less than, or equal to m

Explanation / Answer

the system of masses moves with m2 moving down and m1 moving towards right.

since the mass m2 moves down , hence the weight of mass m2 is greater than the tension force acting on it in upward direction.

on mass m1 , net force T acts in right direction hence it accelerates in right direction so correct choice is

yes, m2 accelerates downward and m1 towards right

since m2 moves down , weight of mass m2 is greater as compared to tension in the string

hence correct choice is T < m2g

mass m1 and m2 are connected by the same string , hence the tension force remains the same for both the masses.

so tension acting on masses are equal in magnitude

T<m2g
