$$
i.e.Angle of prism
Such that,
Let us put
$$
\begin{aligned}
& 1.5=\frac{\sin \left(\frac{A+\delta_{\text {min }}}{2}\right)}{\sin A / 2} \
& \Rightarrow 1.5=\frac{\sin \left(\frac{74^{\circ}+\delta_{\text {min }}}{2}\right)}{\sin 37^{\circ}} \
& \Rightarrow 0.9=\sin \left(37^{\circ}+\frac{\delta_{\text {min }}}{2}\right)\left(\because \sin 37^{\circ} \approx 0.6\right) \
& \sin 64^{\circ}=\sin \left(37^{\circ}+\frac{\delta_{\text {min }}}{2}\right)\left(\because \sin 64^{\circ}=0.9\right) \
& 37^{\circ}+\frac{\delta_{\text {min }}}{2}=64^{\circ} \Rightarrow \delta_{\text {min }} \approx 54^{\circ}

\rho(r) \alpha \frac{1}{r}
$$
Option 4:
$$
\rho(r) \alpha \frac{1}{r^2}
$$
Correct Answer:
$$
\rho(r) \alpha \frac{1}{r}
$$
Solution:
As we learned
Relation between field and potential -
$$
E=\frac{-d V}{d r}
$$
- wherein
If P lies inside -
$$
\begin{aligned}
& E_{i n}=\frac{1}{4 \pi \epsilon_0} \frac{Q r}{R^3} \quad V_{i n}=\frac{Q}{4 \pi \epsilon_0} \frac{3 R^2-r^2}{2 R^3} \
& E_{i n}=\frac{\rho r}{3 \epsilon_0} \quad V_{i n}=\frac{\rho\left(3 R^2-r^2\right)}{6 \epsilon_0}

Some important questions to practice from this chapter are given below:
Q. 1 A cord of negligible mass is wound around the rim of a wheel supported by spokes with negligible mass. The mass of wheel is 10 kg and radius is 10 cm and it can freely rotate without any friction. Initially the wheel is at rest. If a steady pull of 20 N is applied on the cord, the angular velocity of the wheel, after the cord is unwound by 1 m , would be :
Option 1:
20rad/s
Option 2:
30rad/s
Option 3:
10rad/s
Option 4:
0rad/s
Correct Answer:
20rad/s
Solution:
$$
\begin{aligned}
& \mathrm{W}_{\mathrm{F}}=20 \times 1=20 \mathrm{~J} \
& \therefore \quad \Delta \mathrm{KE}=20 \mathrm{~J}=\frac{1}{2} \mathrm{I} \omega^2 \
& \mathrm{I}=\mathrm{MR}^2=10 \times 0.1^2=0.1 \mathrm{~kg} \mathrm{~m}^2 \
& \therefore \quad 20=\frac{1}{2} \times 0.1 \times \omega^2 \
& \Rightarrow \omega=20 \mathrm{rad} / \mathrm{sec}
\end{aligned}
$$
Hence, the answer is the option (1)
Q. 2 In a physical balance working on the principle of moments, when 5 mg weight is placed on the left pan, the beam becomes horizontal. Both the empty pans of the balance are of equal mass. Which of the following statements is correct?
Option 1:
Left arm is longer than the right arm
Option 2:
Both the arms are of same length
Option 4:
Every object that is weighed using this balance appears lighter than its actual weight.
Correct Answer:
Left arm is shorter than the right arm
Solution:
Point of application of force -
The point at which if the net force is assumed to be acting then it will produce the same effect of both translation \& rotation.
For balance
Anticlockwise Moment = Clockwise Moment
i.e. Load × load arm
When 5 mg weight is placed on the left side
the load arm shifts to the left side, hence left arm becomes shorter than the right arm.
Hence, the answer is the option (3).

Bohr quantisation principle -
$$
m v r=\frac{n h}{2 \pi}
$$
- wherein
The angular momentum of an electron in a stationary orbit is quantised.
$$
\begin{aligned}
& \because m v r=\frac{n h}{2 \pi} \Rightarrow v=\frac{h}{2 \pi m r}(n=1) \
& \therefore a=\left(\frac{h}{2 \pi m r}\right)^2 \cdot \frac{1}{r}=\frac{h^2}{4 \pi^2 m^2 r^3}
