Q. No.The two blocks \(A,B\) have identical masses and are placed on a smooth horizontal plane. The pulley \(P\) is light, and is rigidly connected to the block \(A\) by means of a horizontal light rod. The string connecting block \(B\) is also horizontal. A force \(F\) is acting vertically on the string, and the two blocks move horizontally. The force on \(A\) due to rod is:
1. \(F\)
2. \(2F\)
3. \(\sqrt2F\)
4. \(\dfrac{F}{\sqrt2}\)

| Assertion (A): | Newton's law of action and reaction is a consequence of Newton's law of inertia. |
| Reason (R): | Newton's law of inertia implies that any body that is not acted upon by external forces cannot change its state of rest or uniform motion. |
