Explanation:
Given that,
Charge of the particle, q = 8.4 C
Speed of the particle, v = 40 m/s
Magnitude of magnetic field, B = 0.33 T
Let us assumed to find the magnitude and direction of the magnetic force on the particle. Let 30.0 degrees for one, and 150 degrees for two, with a perpendicular charge. So,
[tex]F=qvB\ \sin\theta[/tex]
[tex]F_1=8.4\times 40\times 0.33\times \ \sin(30)[/tex]
[tex]F_1=55.44\ N[/tex]
If angle is 150 degrees
[tex]F_2=8.4\times 40\times 0.33\times \ \sin(150)[/tex]
[tex]F_2=55.44\ N[/tex]
If angle is 90 degrees
[tex]F_3=8.4\times 40\times 0.33\times \ \sin(90)[/tex]
[tex]F_3=110.88\ N[/tex]
Hence, this is the required solution.
