What happens to a positive charge in a magnetic field?

A positive charge, top, moving perpendicularly through a magnetic field is deflected. The right-hand rule, bottom, predicts the direction in which the positive charge will be deflected.

When a positive charge enters a uniform magnetic field?

While the perpendicular component moves the particle in a circle. Thus, the trajectory of the particle is helix. Hence, when a positively charged particle enters into a uniform magnetic field with uniform velocity, its trajectory can be straight line or a circle or a helix. So, the correct answer is “Option D”.

When a positive charge is released from rest in a uniform electric field it will?

When a positively charged particle is released from rest in a uniform field, it moves along the electric field, i.e., from higher potential to lower potential. That is electric potential energy of the charge decreases.

What happens when a charge is placed in uniform electric field?

Electric charges of the same magnitude, whether positive or negative, experience the same magnitude of force when placed in the same uniform electric field.

How do you tell if a charge is positive or negative in a magnetic field?

If you hold out your thumb as if you’re hitch-hiking, your thumb will point in the direction of the force. At least, your thumb points in the direction of the force as long as the charge is positive. A negative charge introduces a negative sign, which flips the direction of the force.

Is out of the page positive or negative?

With the usual orientation of the x-y plane: the positive z direction points out of the page towards you and the negative z direction points into the page away from you.

When a charged particle enters a uniform magnetic field what happens?

When a charged particle enters, parallel to the uniform magnetic field, it is not acted by any force, that is, it is not accelerated. Thus, its speed remains constant, and so does its kinetic energy.

Will a charged particle move when placed at rest in a uniform electric field?

Hint- Since the charged particle with charge q is in a uniform electric field E and the force applied on it will be F, the particle will move in the direction of the electric field with acceleration a.

When a charge is placed at rest in an electric field its path will always be along electric line of force?

If a charge is placed at rest in an electric field, its path will be tangential to the lines of force. When the electric field lines are straight lines then the tangent to them will coincide with the electric field lines so the charge will move along them only.
