Particle D is neutral## Further explanation

Magnetic fields can be generated by:n

The charge of a moving electron experiences a magnetic force.n

The magnetic force (Lorentz) acting on a charge moving in a magnetic field is:n

F = B i l sin u03b1nF = magnetic force, Nn

B = magnetic induction, Wb / mu00b2

i = electric current, An

l = length of conductor, mn

u03b1 = angle between current and magnetic fieldn

The path traveled by the charge over time is proportional to velocity (v = l / t), while the current I = q/tn

so the magnetic force equation becomesn

## F = Bqv sin an

If we look at the picture, the particle enters the magnetic field perpendicularly so that the magnetic force functions as a centripetal forcen

F = Bqv sin 90 = m.ac (ac = centripetal acceleration)n

[tex]displaystyle Bqv=mfrac{v^2}{r}[/tex]

[tex]displaystyle r=frac{mv}{Bq}[/tex]

From this equation shows that the radius of the path of a particle is proportional to its linear velocityn

n

From the picture also shows that particle D is not deflected in a magnetic field, so that

the path moves straight, sothe magnetic force = 0, can also showparticles because there is no magnetic force acting on itneutral charged## Learn moren

Particles B is slowly bent to the right side.

Particle C curves towards the right side.

Particle D is perpendicularly straight.

The particle E bends towards the right side.

Therefore D is showing none deflection then it is the part D which is neutral
