A particle of small mass m is joined to a very heavy body by a light string passing over a light pulley (as in an Atwood machine). Both bodies are free to move. The total downward force on the pulley is nearly

Options:

Answer:

Solution:

For a very heavy body $M ≫ m$ , the Atwood acceleration is almost $g$ .

$T = \frac{2 M m g}{M + m} \approx 2 m g$ .

Total downward force on the pulley $= 2 T \approx 4 m g$ .
