Question

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. `10N`
B. `20N`
C. `32N`
D. `40N`

Answer 1

Correct Answer - 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 equation, we get .
