Dear student
In a velocity selector, charged particles must move at a speed of v=E/B in order to pass through the equipment. Hence, a velocity selector, as it’s name implies, allows charged particles with a certain velocity to pass through (hence, selecting particles of a certain velocity).
The velocity selector will have the following fields:
The velocity selector will have the following fields:
An uniform electric field, which is generated by a positively charged bottom plate and negatively charged top plate. This will cause an electric field to form between the plate, that is pointing in the upwards direction.
An uniform magnetic field throughout the space between the two charged plates. The uniform magnetic field can be directed inwards (into the paper) or outwards (out of the paper). In the figure above, the magnetic field is directed outwards.

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
