Question
1) Are the masses accelerating? HINT: Think about the forces acting on m1
(a)Yes, m2 accelerates downward and m1 accelerates to the right.
(b)No, they move with a constant velocity so they do not accelerate.
(c)Cannot determine unless we know if m1 is greater than, less than, or equal to m2.
(d)No, they stay still so they do not accelerate.
2) How does the tension acting on m2 compare with the weight of m2? HINT: Newton's 2nd Law!
(a)|[(F) ec]T| = m2g
(b)Cannot determine unless we know if m1 is greater than, less than, or equal to m2.
(c)|[(F) ec]T| < m2g
(d)|[(F) ec]T| > m2g
3) How does the magnitude of the tension acting on m1 compare with the magnitude of the tension acting on m2?
(a)The tensions acting on the masses are equal in magnitude.
(b)The tension acting on m1 is larger than the tension acting on m2.
(c)Impossible to tell unless we know if m1 is greater than, less than, or equal to m2.
(d)The tension acting on m2 is larger than the tension acting on m1
4) How does the magnitude of the tension acting on m1 compare with the weight of m2?
(a)|[(F) ec]T| < m2g
(b)|[(F) ec]T| = m2g
(c)|[(F) ec]T| > m2g
(d)Cannot determine unless we know if m1 is greater than, less than, or equal to m2.
Explanation / Answer
1 . (a)Yes, m2 accelerates downward and m1 accelerates to the right.
2. on m2,
as m2 accelerates downwards, so Fnet > 0 in downwards direction.
mg > T
Ans ( c)
3. (a)The tensions acting on the masses are equal in magnitude.
4. it will be same as part2 ,
because tension is same.
Ans(a)
