Final answer:
To find the strength of the magnetic field, we can use the formula for the magnetic force on a charged particle. In this problem, we are given the charge of the particle, its velocity, and the magnetic force. Since the particle is moving perpendicular to the magnetic field, we can rearrange the formula to solve for B.
Step-by-step explanation:
To find the strength of the magnetic field, we can use the formula for the magnetic force on a charged particle:
F = qvBsinθ
Where F is the force, q is the charge of the particle, v is the velocity of the particle, B is the magnetic field strength, and θ is the angle between the velocity and the magnetic field.
In this problem, we are given the charge of the particle (2.0x10⁻⁶C), its velocity (3x10⁶ m/s), and the magnetic force (0.5 N).
Since the particle is moving perpendicular to the magnetic field, sinθ = 1. Therefore, we can rearrange the formula to solve for B:
B = F / (qv)
Plugging in the given values, we get:
B = 0.5 N / (2.0x10⁻⁶C)(3x10⁶ m/s) = 8.3x10⁻⁵ T
Therefore, the strength of the magnetic field is 8.3x10⁻⁵ T.
