A block of mass `3kg` which is on a smooth inclined plane making angie of `30^(@)` to the horizontal is connected by cord passing over light frictionless pulley to second block of mass `2kg` hanging vertically. What is the acceleration of each block and waht is the tension of the cord ? .

Options

A. `0.98 m//s^(2), 17.6 N`
B. `1.98 m//s^(2), 19.6 N`
C. `0.49 m//s^(2), 9.8 N`
D. `1.47 m//s^(2), 4.9 N`

Answer

A

Explanation

`m_(1) g -T =m_(1) a,T -m_(2) g sin theta = m_(2)a` .
