Question

A block of mass 6 kg is applied on a frictionless table.a thread tied to it passes over a frictionless
pulley and carries a body B of mass 4 kg at the other end.Find the acceleration of the system and tension in the thread (given g = 10 ms-2)
1) a = 6 m/s2; T = 30 N
2) a = 2 m/s2; T=22N
3) a = 4 m/s2; T = 24 N
4) a = 8 m/s2; T = 28 N​

Answer 1

Answer:

a = 4 m/s2. T=24N

Explanation:

For 6kg block

T = 6a

as it is on frictionless table

For 4kg block

mg-T=ma

40-T=4a

Putting T=6a

40-6a=4a

40=10a

a = 4m/s2

T=6a

=6×4

=24N
