MCQ
Point $A$ is at a lower electrical potential than point $B$. An electron between them on the line joining them will:
- AMove towards $A$
- ✓Move towards $B$
- CMove at right angles to the line joining $A$ and $B$
- DRemain at rest
✓
Answer
Correct option: B.
Move towards $B$
Given that point $A$ is at lower electric potential than point $B$. The electron between them on line joining will move.
We have to find where this electron moves.
Since we know that electric currents move from a higher potential or a lower potential. Also, electrons move in the direction opposite to electric current. So the electron on the line joining two points $A$ and $B$ will move from lower to higher potential i.e, it will move towards $B.$

→A dense collection of equal number of electrons and positive ions is called neutral plasma. Certain solids containing fixed positive ions surrounded by free electrons can be treated as neutral plasma. Let ' $N$ ' be the number density of free electrons, each of mass ' $m$ '. When the electrons are subjected to an electric field, they are displaced relatively away from the heavy positive ions. If the electric field becomes zero, the electrons begin to oscillate about the positive ions with a natural angular frequency ' $\omega_p$ ', which is called the plasma frequency. To sustain the oscillations, a time varying electric field needs to be applied that has an angular frequency $\omega$, where a part of the energy is absorbed and a part of it is reflected. As $\omega$ approaches $\omega_{ p }$, all the free electrons are set to resonance together and all the energy is reflected. This is the explanation of high reflectivity of metals.
