describe the behaviour of beams of protons, neutrons and electrons moving at the same velocity in anelectric fie

In an electric field, the behavior of protons, neutrons, and electrons moving at the same velocity will differ due to their different charges and masses.

1. Protons: Protons are positively charged particles. When a beam of protons enters an electric field, they will be attracted towards the negatively charged plate (assuming a parallel plate setup). The path of the protons will curve due to this attraction. The degree of curvature will depend on the strength of the electric field and the initial velocity of the protons.

2. Neutrons: Neutrons are neutral particles, meaning they have no charge. Because of this, they are not affected by electric fields. A beam of neutrons moving at a certain velocity will continue to move in a straight line when it enters an electric field.

3. Electrons: Electrons are negatively charged particles. When a beam of electrons enters an electric field, they will be attracted towards the positively charged plate. Like protons, the path of the electrons will curve, but in the opposite direction due to their opposite charge. The degree of curvature will again depend on the strength of the electric field and the initial velocity of the electrons.

In summary, in an electric field, protons and electrons will deviate from their path due to the force exerted by the field, while neutrons will continue in a straight line due to their lack of charge.
