Question

A block of mass m on a smooth horizontal surface is connected to a second mass 2 m by a light cord of a light frictionless pulley as shown. (Neglect the mass of the cord and of the pulley). A force of magnitude F0 is applied to mass m as shown. Neglect any friction. Find the value of force F0 for which the system be in equilibrium

Answer 1

Answer:

Explanation:

Since we have asked the system should be in equilibrium...

So the net force should be zero .

Hence no acceleration will be there

For 2m :

T=2mg

And for m:

F0=2T ; T = 2mg

F0 =4mg

Answer 2

Answer:

Explanation:
