Which one of the following is deflected in electric field?
The alpha rays and beta rays get deflected by the electric field. Alpha rays are positively charged and beta rays are negatively charged.
Which particle is deflected the most in an electric field?
electrons
What happens to a positive particle in an electric field created by a proton?
The arrow heads show the direction in which a positively charged particle (such as a proton) would accelerate if it was placed in the electric field. A negatively charged particle (such as an electron) would accelerate in the opposite direction to the arrow heads.
What happens when a proton moves perpendicular to a magnetic field?
Since the proton’s velocity is in +z direction and force due to the magnetic field is accelerating the proton in +x direction, therefore, from the right-hand rule, it is clear that the direction of the magnetic field will be in −y direction.
Which property of a proton can change while it moves freely in a magnetic field?
The magnetic force acts perpendicular to the direction of motion of the proton. It does not change its mass and speed but changes its direction of motion. So both velocity and momentum get changed.
When positively charged particle is projected towards West?
A positively-charged particle (alpha-particle) projected towards west is deflected towards north by a magnetic field.
Which of the following is not the source of magnetic field?
A static electric charge does not have a moving current; it is just an accumulation of cations or anions, this does not cause a magnetic field. A moving light source does not carry any sort of charge or magnetic force or any sort of force hence it cannot be a source of the magnetic field.
Why does the momentum of a proton changes when it enters a magnetic field?
The magnetic force exerted will be perpendicular to the direction of motion of the proton. The force is able to change the direction (velocity) of the proton but not its speed (magnitude). Thus momentum and velocity changes.
Can the speed of a proton changes while it moves freely in a magnetic field?
Each moving charged particle in a magnetic field experiences a force. Fleming’s left-hand rule gives the direction of force experienced by a positive charge (i.e., a proton). The force can change the direction (velocity) of the proton but not its speed (magnitude). Thus, momentum and velocity changes.
Can magnetic force change the momentum of moving charged particle?
The magnetic field can change the directions of the motions of the charged particles, but it will not change their speeds. In other words, the kinetic energy is constant in time.
