| Jun 4, 2023 at 12:06 | comment | added | user3423423 | Oh, I see: when the mass is very small, some amount of resultant force will in fact be present (part of the force applied by the person is expended on the rope, and part on the block), and the rope will accelerate as expected. | |
| Jun 4, 2023 at 12:03 | comment | added | Amit | Welcome! I think that you could have saved the intermediate steps, and immediately conclude that the sum of forces acting on a massless rope is $0$ because $ma$=$0a$=$0$! It seems to me then that the culprit is applying Newton's second law to an idealized massless rope. Perhaps this post can help you in this regard | |
