A charged particle enters into a uniform magnetic field such that its velocity vector is perpendicular to the magnetic field vector. Ignoring the particle's weight, what type of path will the particle follow?
A) follow a spiralpath.
B) move in a straight line. C) move along a parabolic path.
D)follow a circular path.

The particle path will follow

(d) a circular path

Explanation:

When a charged particle having charge of magnitude '' enters into a magnetic field such that its velocity vector '' is perpendicular to the direction of the magnetic field '', then it will experience a force, called Lorentz force (), given by

As shown in the figure, the magnetic field is directed perpendicular to the plane and towards the plane (as shown by the circle and 'X'-sign) and the velocity vector is from left to right on the plane.

According to the property of cross-product, the Lorentz force () acting on the particle will be perpendicular to the instantaneous position of the particle, making the path of the particle to be a circular path,as shown in the figure.

it doesn't. it was imagined up in the middle ages.

i think it's 35 meters
