Draw an electric circuit with a cell, key, ammeter, a resistor (series) of 2 ohm with combination of two resistors (4 ohm each) in parallel and a voltmeter across parallel combination.

As per the question, Will the potential difference across the 2 Ω resistor be similar to the one across the parallel combination with 4Ω resistors? The following reasons can be illustrated:

Step 1: Circuit Diagram

The circuit diagram with a cell, key, ammeter, resistors in series (2 $\Omega$) with a combination of two resistors can be represented as:

Electric Circuit Diagram

Step 2: Solution

Effective resistance of the parallel connected combination of two resistors is:

R_eff = ${4\ \times\ 4} \over {4\ +\ 4}$

⇒ R_eff = ${{16} \over 8}$

⇒ R_eff = 2Ω

Hence, because of the 2 Ω resistor and the parallel combination of two 4 Ω resistors are connected in series, the flow of current will be in the same direction. Due to this reason, the potential difference that occurs between the two-ohm resistors is similar to the potential difference between two resistors jointly.

A charged particle $+q$ in an electric field $\vec{E}$ experiences a force in the direction of the electric field. As a result, its kinetic energy changes. Similarly, the charged particle also experiences a force when it moves in a magnetic field $\vec{B}$. But this magnetic force is perpendicular to both velocity $\vec{v}$ of the charged particle and the magnetic field $\vec{B}$, so it cannot change the kinetic energy of the charged particle. Consider two charged particles 1 and 2 of masses $m$ and $\frac{m}{2}$ having charges $-q$ and $+2q$ respectively. They are accelerated from rest through the same potential difference $V$ and acquire kinetic energy $K_1$ and $K_2$. Then they enter in a region of uniform magnetic field $\vec{B}$ perpendicular to their velocities.
