An electron is moving through a magnetic field whose magnitude is 9.21 × 10^-4 t. the electron experiences only a magnetic force and has an acceleration of magnitude 2.30 × 10^14 m/s^2. at a certain instant, it has a speed of 7.69 × 10^6 m/s. determine the angle (less than 90°) between the electron's velocity and the magnetic field.

Explanation:

Given that,

Magnetic field,

Acceleration of the electron,

Speed of electron,

The force due to this acceleration is balanced by the magnetic force as :

So, the angle between the electron's velocity and the magnetic field is 10.6 degrees. Hence, this is the required solution,

he . if i may ask what i your question exactly?

explanation:

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
