A charge of -8.5 µC is traveling at a speed of 9.0 106 m/s in a region of space where there is a magnetic field. The angle between the velocity of the charge and the field is 56°. A force of magnitude 5.9 10-3 N acts on the charge. What is the magnitude of the magnetic field?

Answer :

Answer:

The magnitude of the magnetic field is [tex]9.3\times 10^{-5}\ T[/tex].

Explanation:

Given that,

Charge, [tex]q=-8.5\ \mu C=-8.5\times 10^{-6}\ C[/tex]

Speed of the charged particle, [tex]v=9\times 10^6\ m/s[/tex]

The angle between the velocity of the charge and the field is 56°.

The magnitude of force, [tex]F=5.9\times 10^{-3}\ N[/tex]

We need to find the magnitude of the magnetic field. When a charged particle moves in the magnetic field, the magnetic force is experienced by it. The force is given by :

[tex]F=qvB\ \sin\theta[/tex]

B is the magnetic field.

[tex]B=\dfrac{F}{qv\ \sin\theta}\\\\B=\dfrac{5.9\times 10^{-3}}{8.5\times 10^{-6}\times 9\times 10^6\ \sin(56)}\\\\B=9.3\times 10^{-5}\ T[/tex]

So, the magnitude of the magnetic field is [tex]9.3\times 10^{-5}\ T[/tex]. Hence, this is the required solution.
