Two blocks are arranged as shown on a smooth horizontal surface. A force F is exerted on the small block m. Which of the following statements are true?

Options:

Answer:

Solution:

Treat both blocks as one system on the smooth surface: $F = (m + M) a \Rightarrow a = \frac{F}{m + M}$ .

Normal force by $m$ on $M$ : $N = M a = \frac{MF}{m + M} < F$ .

By Newton's third law the force by $m$ on $M$ equals the force by $M$ on $m$ , so (C) and (D) are false.
