Question

A uniform pole of length ???? = 2 L is laid on smooth horizontal
table as shown in figure. The mass of pole is M and it is
connected to a frictionless axis at O.A spring with force
constant k is connected to the other end. The pole is
displaced by a small angle ϴ₀ from equilibrium position and
released such that it performs small oscillations. Then
(a) ⍵₀ = √M/3k (b) ⍵₀ = √k/3M
(c) ⍵₀ = √3k/M (d) ⍵₀ = √k/2M

Answer 1

Explanation:

A uniform pole of length ???? = 2 L is laid on smooth horizontal

table as shown in figure. The mass of pole is M and it is

connected to a frictionless axis at O.A spring with force

constant k is connected to the other end. The pole is

displaced by a small angle ϴ₀ from equilibrium position and

released such that it performs small oscillations. Then

(a) ⍵₀ = √M/3k (b) ⍵₀ = √k/3M

(c) ⍵₀ = √3k/M (d) ⍵₀ = √k/2M
