Correct Option - 3

Detailed Solution:

$T = 2 π \sqrt[]{\frac{l}{g}}$

$\Rightarrow 2 = 2 π \sqrt[]{\frac{2}{g}}$

$\Rightarrow g = 2 π^{2} m / s^{2}$

Raj Pandey

$A_{1} = \sqrt[]{{(5)}^{2} + {(5 \sqrt[]{3})}^{2}} = 10$

$A_{2} = 5$

Then, $\frac{A_{1}}{A_{2}} = \frac{10}{5} = \frac{2}{1}$

For an SHM oscillator, the amplitude is 5 cm and its time period is 4 seconds. The minimum time taken by the particle to pass between points which are at distances 4 cm and 3 cm from the centre of oscillation on the same side of it will be

$y = A \sin ? \frac{2 π t}{T}$

$t_{2} - t_{1} = \frac{T}{2 π} [\sin^{- 1} ? \frac{x_{1}}{A} - \sin^{- 1} ? \frac{x_{2}}{A}]$

The given arrangement is in vertical plane and initially the springs are in natural length. The uniform rod is hinged at end O, about which it can freely rotate. The angular frequency of small oscillations of the rod is n/8 √(k/m). Find n. (Given: m = mass of rod, L = length of rod and k = mg/L)

Vishal Baghel

Given mg = kL
∴ Iα = (kLθ.L + k (L/2)²θ - mg (L/2)θ)
(mL²/3)α = kL² (3/4)θ (restoring torque)
α = (9k/4m)θ
∴ ω = (3/2)√ (k/m)

Vishal Baghel

y = A sin (2πt/T)
t? - t? = (T/2π) [sin? ¹ (x? /A) - sin? ¹ (x? /A)]

A body is executing simple harmonic motion with frequency ' $n$ ', the frequency of its potential energy is:

alok kumar singh

Displacement equation of SHM of frequency ' $n$ '

$x = A s i n ? (ω t) = A s i n ? (2 π n t)$

Now,

Potential energy $U = \frac{1}{2} {k x}^{2} = \frac{1}{2} {K A}^{2} {s i n}^{2} ? 2 π n t$

$= \frac{1}{2} {k A}^{2} [\frac{1 - c o s ? 2 π 2 n t}{2}]$

So frequency of potential energy $= 2 n$
