Three block of masses `m_1, m_2 & M_3` are connected by mass less stings as shown on a frictionless table.

They are pulled with a force `T_(3)=40N," If "m_(1)=10kg, m_(2)=6kg & m_(3)=4kg`, then tension `T_(2)` will be

A

20N

B

40N

C

10

D

32N

Text Solution

Verified by Experts

The correct Answer is:
D
Net acceleration `=(T_(3))/(m_(1)+m_(2)+m_(3))=40/20=2m//s^(2)`
`T_(2)=(m_(1)+m_(2))a=16 xx 2=32N`
