PhysicsEasysingle choice

Two blocks of masses $m_{1} = 4$ kg and $m_{2} = 2$ kg are connected to the ends of a string which passes over a massless, frictionless pulley. The total downwards thrust on the pulley is nearly

Options:

Answer:

Solution:

$T = \frac{2 m_{1} m_{2}}{m_{1} + m_{2}} g = \frac{2 \times 4 \times 2 \times 10}{4 + 2}$

$= \frac{160}{6} = 26.6 = 27 N$

Total downward thrust on the pulley

$= 2 T = 2 \times 27 = 54$ N
