Answer:
Explanation:
F restoring = F friction
F friction = Ц mg
F restoring = mw²A
Restoring force on the block = mω2A = μmg.
∴ Acceleration in the block = μg
Frequency of oscillation,
v = 1 / 2 √acceleration / Displacement
= 1/2 π √μg / A

When the block just starts to slip the time period will be .
Explanation:
The displacement of particle from its mean position is given by :
Where
k is the propagation constant
is the angular speed
A is the amplitude of wave
When the mass m just starts to slip, then the condition is given by :
maximum restoring force = limiting friction force
`Since,
T is the period
Hence, when the block just starts to slip the time period will be . Hence, this is the required solution.
