Question

two bodies of masses 1 kg and 2 kg are connected by a very light string passed over a clamped light smooth pulley if the system is released from rest find the acceleration of the two masses and the tension in the string
1) 3.27 m/s²; 13N
2) 4.5 m/s²; 26N
3) 1.27 m/s²; 13N
4) 0.327 m/s²; 13N

Answer 1

Here body of mass 2 kg will move down and mass 1 kg moves up with same acceleration

write equations

2g-T=2a ---------- (1)

T-1g=1a ------------(2)

add both eqs

g=3a or

a=g/3= 10/3=3.33 m/s^2

putting value of a in eq 2 we get

T=10+(10/3) or

T=40/3= 13.33 N
