Why is the path of a charged particle not a circle when it is velocity is not perpendicular to the magnetic field?
If a charged particle moves in a region of a uniform magnetic field such that its velocity is not perpendicular to the magnetic field, then the velocity of the particle is split up into two components. Hence the path of the particle is not a circle; it is helical around the field lines.
Why is the path of a charged particle not a circle?
Answer: Since the magnetic force is perpendicular to the direction of travel, a charged particle follows a curved path in a magnetic field. The magnetic force is perpendicular to the velocity, so velocity changes in direction but not magnitude. The result is uniform circular motion.
Why does a magnetic field do not work on a charged particle?
One basic feature of magnetism is that, in the vicinity of a magnetic field, a moving charge will experience a force. Interestingly, the force on the charged particle is always perpendicular to the direction it is moving. Hence magnetic forces do no work on charged particles and cannot increase their kinetic energy.
Why does not a charged particle moving at right angle to the direction of an electric field follow a circular path?
A charged particle moving at right angle to the direction of the electric field experiences force in the plane of electric filed. Since the force on the charged particle does not remains always perpendicular to the path, it does not move along with the circular path.
Does magnetic force do work on charged particle?
An electric field may do work on a charged particle, while a magnetic field does no work. The Lorentz force is the combination of the electric and magnetic force, which are often considered together for practical applications. Electric field lines are generated on positive charges and terminate on negative ones.
How does a charged particle move in crossed uniform electric and magnetic fields?
The motion of a charged particle in the electric and magnetic field. In case of motion of a charge in a magnetic field, the magnetic force is perpendicular to the velocity of the particle. The particle, therefore, acquires velocity in the y-direction and resulting motion is a helical motion.
What are the major concepts of Dalton’s atomic theory?
The first part of his theory states that all matter is made of atoms, which are indivisible. The second part of the theory says all atoms of a given element are identical in mass and properties. The third part says compounds are combinations of two or more different types of atoms.

The characteristics of cathode rays depend on the material from which they are emitted is the only statement among the following which is not true concerning Cathode Rays.
