Three blocks of masses m(1), m(2) and m(...

Three blocks of masses `m_(1), m_(2) and m_(3)` are connected by a massless string as shown in figure on a frictionless table. They are pulled with a force `T_(3) = 40N`. If `m_(1) = 10kg, m_(2) = 6kg and m_(3) = 4kg`, then tension `T_(2)` will be

A

10 N

B

20 N

C

32 N

D

40N

Text Solution

Verified by Experts

The correct Answer is:
C
`F_("net")=ma, T_(3)-T_(2)=m_(3)a, T_(2)-T_(1)=m_(2)a, T_(1)=m_(1)a`
Solving the above equations, we get
