Question 1: Palette 1/4

AIIMS 2018 MCQ

A block of rectangular size of mass $m$ and area of cross-section $A$, floats in a liquid of density $\rho$. If we give a small vertical displacement from equilibrium, it undergoes SHM with time period $T$, then

$T^2 \propto \frac{1}{\rho}$

$T^2 \propto \rho$

$T^2 \propto m^{-1}$

$T^2 \propto \frac{1}{A^{-2}}$

Question 2: Palette 2/4

AIIMS 2018 MCQ

Assertion A pendulum is falling freely its time period becomes zero.

Reason Freely falling body has the acceleration equal to g.

Both Assertion and Reason are correct, Reason is the correct explanation of Assertion

Both Assertion and Reason are correct but Reason is not the correct explanation of Assertion

Assertion is correct and Reason is incorrect

Assertion is incorrect and Reason is correct

Question 3: Palette 3/4

AIIMS 2017 MCQ

AIIMS 2017 Physics - Oscillations Question 1 English

A load of mass $m$ falls from a height $h$ on the scale pan hung from a spring as shown. If the spring constant is $k$ and mass of the scale pan is zero and the mass $m$ does not bounce relative to the pan, then the amplitude of vibration is

$m g$

$\frac{m g}{k} \sqrt{1+\frac{2 h k}{m g}}$

$\frac{m g}{k}+\frac{m g}{k} \sqrt{\frac{1+2 h k}{m g}}$

None of the above

Question 4: Palette 4/4

AIIMS 2017 MCQ

Assertion : A spring of force constant $k$ is cut into two pieces having lengths in the ratio 1 : 2. The force constant of series combination of the two parts is $\frac{3 k}{2}$.

Reason : The spring connected in series are represented by $k=k_1+k_2$

Both assertion and reason are true and reason is the correct explanation of assertion

Both assertion and reason are true but reason is not the correct explanation of assertion

Assertion is true but reason is false

Both assertion and reason are false.
