Answer:
v = -227.785 m/s
Explanation:
The electric field exerts the following force on the electric particle:
F = qE
[tex]F = 6.65 \times 10^{-6} \times 1230[/tex]
[tex]F = 0.0081795 \ N[/tex]
The magnetic field exerts the following force on the particle::
F = qvB
[tex]F = 6.65\times 10^{-6} \times v \times 1.32[/tex]
[tex]F = 8.778 \times 10^{-6} \times v[/tex]
Total force acting is:
F = qvB + qE
[tex]6.18 \times 10^{-3} = 0.0081795 + 8.778 \times 10^{-6} \times v[/tex]
[tex]v = \dfrac{6.18 \times 10^{-3} -0.0081795 }{8.778 \times 10^{-6}}[/tex]
v = -227.785 m/s
