Hint:The presence of a charge in a magnetic field exerts a force on it. This force is dependent on the intensity of the magnetic field as well as the motion of the charge.
Formula used:
\[F = qvB\sin \theta \], where F is the force exerted on the particle with charge q, moving in a magnetic field with intensity B and at an angle \[\theta \]. The SI unit of this force is Newton (N).
Complete step by step answer
The magnetic field exerts a force only on a moving charged particle. This is because the motion of a charge is associated with current flow, which gives rise to a magnetic field around it. The direction of the force acting on a charged particle in a magnetic field is determined using the right hand thumb rule.
In this question, we are provided with the following information:
Charge of the particle \[q = 200\mu C = 200 \times {10^{ - 6}}C\] [As \[1\mu C = {10^{ - 6}}C\]]
Angle with the magnetic field \[\theta = 30^\circ \]
Magnetic field intensity \[B = 5 \times {10^{ - 5}}Wb/{m^2}\]
Speed of the particle \[v = 2 \times {10^5}m/s\]
We know that the force exerted on the particle is given as:
\[F = qvB\sin \theta \]
Substituting the known values in this equation, we get:
\[\Rightarrow F = 200 \times {10^{ - 6}} \times 2 \times {10^5} \times 5 \times {10^{ - 5}} \times \sin 30\]
\[\Rightarrow F = 2 \times {10^{ - 3}} \times \dfrac{1}{2} = {10^{ - 3}}N\]
Hence, this is the force experienced by the particle in the given conditions.
Note: When a charged particle moves at some angle with the uniform magnetic field exerted on it, a helical motion is generated. Due to this helical motion of particles trapped in a magnetic field, a very peculiar phenomenon of the Aurora is observed both in the Northern and the Southern hemispheres.
