Two blocks of masses 6 kg and 4 kg are connected b a rope of mass 2 kg are resting on a frictionless floor as shown in the following figure:

In a constant force of 60N is applied to 6 kg block then the tension in the rope at points A,B and C are respectively given by :

Options

A. 60N,60N,60N
B. 30N,25N,20N
C. 20N,25N,30N
D. 20N,20N,20N

Answer

B

Explanation

`a=(60)/(10)=5 m//s^(2)`
`T_(c)=4xx5=20`
`T_(A)=60-6xx5=30`
`T_(B)=5xx5=25`
