Question
Using Bohr model, calculate the electric current created by the electron when the H-atom is in the ground state.
✓
Answer
v = velocity of electron, $a_0=$ Bohr radius. Number of revolutions per unit time $=\frac{2\pi\text{a}_0}{\text{V}_0}$So, current $=\text{i}=\frac{2\pi\text{a}_0}{\text{v}}\text{e}.$

The electric field E due to a point charge at any point near it is defined as $\text{E} = \DeclareMathOperator*{\median}{\text{lim}} \median_{\text{q}\rightarrow0}\frac{\text{F}}{\text{q}}$ where q is the test charge and F is the force acting on it. What is the physical significance of $\DeclareMathOperator*{\median}{\text{lim}} \median_{\text{q}\rightarrow0}$ in this expression? Draw the electric field lines of a point charge Q when (a) Q>0 and (b) Q<0.

Spring fitted doors close by themselves when released. You want to keep the door open for a long time, say for an hour. If you put a half kg stone in front of the open door, it does not help. The stone slides with the door and the door gets closed. However, if you sandwitch a 20g piece of wood in the small gap between the door and the floor, the door stays open. Explain why a much lighter piece of wood is able to keep the door open while the heavy stone fails.
