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

Options

A. 18 N
B. 9 N
C. `3.375 N`
D. `1.75 N`

Answer

B

Explanation

`a=F//(m_(1)+m_(2)+m_(3))=36//(1+8+27)=1m//s^(2)`
`T_(2)=(m_(1)+m_(2))a=(1+8)xx1=9N`
