Question

A 2 kg block is lying on a smooth table which is connected by a body of mass 1 kg by a string which passes through a pulley. The 1 kg mass is hanging vertically. The acceleration of block and tension in the string will be

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

$Accerleration=\frac{m_2}{m_1+m_2}\times g=\frac{1}{2+1}\times 9.8=3.27m/s^2$

and $T=m_{1}a=2\times 3.27=6.54N$
