Gamma rays are high energy electromagnetic waves which do not have a net electrical charge. This means that alpha and beta radiation can be deflected by electric fields, but gamma radiation cannot. Hence the types of waves that cannot be deflected by an electric field or a magnetic field are gamma rays.

In a magnetic field the force is always at right angles to the motion of the electron (Fleming’s left hand rule) and so the resulting path of the electron is circular (Figure 1). Charged particles move in straight lines at a constant speed if projected into a magnetic field along the direction of the field.

Only charged particles can interact with electric field. Neutrons are charge-less. Alpha particle are basically helium nuclei and are charged. So they are deflected in electric field.

Alpha particles are positively charged and are therefore attributed to the negative plate in an electric field. Was this answer helpful?

To detect the electric fields, use a conducting rod. The fields cause charges (generally electrons) to accelerate back and forth on the rod, creating a potential difference that oscillates at the frequency of the EM wave and with an amplitude proportional to the amplitude of the wave.

Electric field lines never intersect. The electric field lines can never form closed loops, as line can never start and end on the same charge. These field lines always flow from higher potential to lower potential. If the electric field in a given region of space is zero, electric field lines do not exist.

Electric field lines tell us the direction of the electric field at any point. Electric field lines give us the indication of the strength of the electric field o strength of the force at any point.

Properties of an Electric Field

• Field lines never intersect each other.
• They are perpendicular to the surface charge.
• The field is strong when the lines are close together, and it is weak when the field lines move apart from each other.
• The number of field lines is directly proportional to the magnitude of the charge.

Properties of Electric Field Lines. The field lines never intersect each other. The field lines are perpendicular to the surface of the charge. The magnitude of charge and the number of field lines, both are proportional to each other.

Electric field is zero inside a charged conductor. For a charged conductor, the charges will lie on the surface of the conductor.So, there will not be any charges inside the conductor. When there is no charge there will not be electric field.

Electric field lines are not parallel and equidistant. …

As mentioned in the hint, a uniform electric field is which remains constant in space regardless of the point where we are measuring it. So, a point charge does not create a uniform electric field. Again, the electric field decreases with increasing distance from the line so it does not create a uniform electric field.

“At any point in an electric field the electric potential is the amount of electric potential energy divided by the amount of charge at that point. It takes the charge quantity out of the equation and leaves us with an idea of how much potential energy specific areas of the electric field may provide.”

An electric field is a region where a charged particle (such as an electron or proton) experiences a force (an electrical force) without being touched. If the charged particle is free to move, it will accelerate in the direction of the unbalanced force. Work is done when a charge is moved in an electric field.

The normal to the surface can point into two different directions. For a closed surface, by convention, the normal points outward. With our definition of A we can write the flux as the dot product of E and ΔA. ΔΦE = E∙ΔA = Eperpendicular*ΔA = E ΔA cosθ.

The electric flux through a surface is proportional to the number of field lines crossing that surface. Note that this means the magnitude is proportional to the portion of the field perpendicular to the area.
