A rope of length 4 m having mass 1.5 kg/...

A rope of length 4 m having mass 1.5 kg/m lying on a horizontal frictionless surface is pulled at one end by a force of 12N. What is the tension in the rope at a point 1.6 m from the other end?

A

5N

B

4.8N

C

7.2N

D

6N

Text Solution

Verified by Experts

The correct Answer is:
B
As in fig. the mass of the rope `:m=4xx1.6 =6 = kg`
Acceleration `:a=12//+=2m//s^(2)`

Mass of part 1 as a in fig. `m_(1)=1.6xx1.5=2.4 kg T m_(1)a`
`=2.4xx2=4.8 N`
