Three blocks are connected as shown in figure on `a` horizontal frictionless table. If `m_(1)=1kg` , `m_(2)=8kg` , `m_(3)=27kg` and `T_(3)=36N` , `T_(2)` will be.

A

18N

B

9N

C

`3.375N`

D

`1.75N`

Text Solution

Verified by Experts

The correct Answer is:
B
`T_(3)=(m_(1)m_(2)+m_(3))a`
implies `36=(1+8+27)a` implies `a=1m//s^(2)`
Now `T_(2)=(m_(1)+m_(2)a=(1+8)xx1=9N`
