A block of mass 0.2 kg is suspended from the ceiling by a light string. A second block of mass 0.3 kg is suspended from the first block through another string. Find the tensions in the two strings. Take `g=10 m/s^2`.

Options

A. `T_(1) = 3 N, T_(2) = 5 N`
B. `T_(1) = 4 N, T_(2) = 3N`
C. `T_(1) = 5 N, T_(2) = 5 N`
D. `T_(1) =3 N, T_(2) = 3 N`

Answer

A

Explanation

`T_(1) -3 =0` [Equilibrium of lower block]
`T_(2) -T_(1) -2=0` [Equilibrium of upper block]
`rArr T_(2) = 5 N`
