1.

There blocks of masses `m_(1)` , `m_(2)` and `m_(3)` are connected by may less unstretchable strings on a smooth surface. Tension `T_(2)` is. A. `2.3N`B. `32N`C. `23N`D. `3.2N`

Answer» Correct Answer - B
Aceleration, `a=(F)/(m_(1)+m_(2)+m_(3))`
`=(40)/(10+6+4)=2ms^(-2)`
Tension `T_(2)=(m_(1)+m_(2))a`
`=(10=6)2=32N` .
