A 6.80 $\mu C$ particle moves through a region of space where an electric field of magnitude 1230 N/C points in the positive $x$

direction, and a magnetic field of magnitude 1.32 T points in the positive $z$ direction. If the net force acting on the particle is 6.18E-3 N in the positive $x$ direction, calculate the magnitude of the particle's velocity. Assume the particle's velocity is in the $x$-$y$ plane.

Answer:

v = -227.785 m/s

Explanation:

The electric field exerts the following force on the electric particle:

F = qE

F = 6.65 \times 10^{-6} \times 1230

F = 0.0081795 \ N

The magnetic field exerts the following force on the particle::

F = qvB

F = 6.65\times 10^{-6} \times v \times 1.32

F = 8.778 \times 10^{-6} \times v

Total force acting is:

F = qvB + qE

6.18 \times 10^{-3} = 0.0081795 + 8.778 \times 10^{-6} \times v

v = \dfrac{6.18 \times 10^{-3}  -0.0081795 }{8.778 \times 10^{-6}}

v = -227.785 m/s

An ion with charge of Q = +3.2 x 10-19 C is in a region where a uniform electric field of magnitude E = 5.0 X 105 V/m is perpend
san4es73 [151]

Answer:

option C

Explanation:

given,

Q = +3.2 x 10⁻¹⁹ C

E = 5.0 X 10⁵ V/m

B = 0.80 T

ion's acceleration is zero  

when acceleration is zero the magnitude of both the forces becomes equal.

q E = q V B

v = \dfrac{E}{B}

v= \dfrac{5 \times 10^5}{0.80}

v = 6.25 × 10⁵ m/s ≈ 6.3 × 10⁵ m/s

hence, the correct answer is option C
