Question

An electron is moving in a circular path in a magnetic field intensity B then its time period is independent of

[Answer Options are:]

(a) Speed (b) mass ( c) charge (d) magnetic field
​

Answer 1

Answer:

The correct answer is Option (a)speed.

Explanation:

An electron is moving in a circular path in a magnetic field intensity B then its time period is independent of speed.

• The time taken by the electron to complete one revolution is known as its time period.
• The time period is given as-

    $T=\frac{2\pi m}{qB}$, Where m is the mass, q is the magnitude of charge, B is the magnetic feild.

• The time period of the moving electron is independent of the speed of the electron and the angle between the magnetic field and the velocity.
• The time period depends on the mass, charge, and magnetic field intensity.

Answer 2

Answer:

An electron is moving in a circular path in a magnetic field intensity B then its time period is independent of speed i.e.option(a).

Explanation:

The time period of an electron moving in a circular path is given as,

$\mathrm{T=\frac{2\pi m}{qB} }$             (1)

Where,

T=time period of an electron moving in a circular path

m= mass of the electron

q=charge on an electron

B= the magnetic region on which the charge is moving

From equation (1) we can analyze that the time period of an electron depends on the following factors:

• The mass of the electron.
• The charge on an electron.
• The magnetic field in which the electron is moving.

So, the correct answer among the given options is (a) Speed.
