Two blocks of equal mass m are tied to each other through a light string. One of the blocks is pulled along the line joining them with a constant force F. Find the tension in the string joining the blocks.

Answer:

                 by considering the two masses as system \[F=2m\,\,a\Rightarrow a=\frac{F}{2m}\]                             ..... (1) Draw F.B.D for mass A. \[T=ma=m\times \frac{F}{2m}=\frac{F}{2}N\]    \[\therefore \]Tension \[T=\frac{F}{2}N\]
