A classical mechanics problem by Abhiram Rao

Classical Mechanics Level 2

A block of mass $M$ is pulled along a horizontal frictionless surface by a rope of mass $m$ . If a force $P$ is applied at the free end of the rope, the force exerted by the rope on the block will be $\text{\_\_\_\_\_\_\_\_\_\_}$ .

PM/M+m Pm/M+m P PM/M-m

$Let\quad the\quad tension\quad in\quad the\quad rope\quad connecting\quad block\quad M\quad and\quad block\quad m\quad be\quad 'T",\quad and\quad \\ the\quad acceleration\quad of\quad both\quad the\quad blocks\quad be\quad 'a'.\\ \\ \\ \therefore \quad a\quad =\quad \frac { P }{ (m+M) } \\ \\ ⇒\quad T\quad =\quad \frac { MP }{ (m+M) } .$
