PhysicsEasysingle choice

The system is pushed by a force $F$ as shown in the figure. All surfaces are smooth except between $B$ and $C$ . Friction coefficient between $B$ and $C$ is $μ$ . Minimum value of $F$ to prevent block $B$ from downward slipping is

Options:

Answer:

Solution:

$N_{C} = \frac{F}{5 m} (2 m) = \frac{2 F}{5}$

Since block $B$ is not falling therefore.

$μ N_{C} = m g$

$μ (\frac{2 F}{5}) = m g$

$F = (\frac{5}{2 μ}) m g$
