Explanation:
Given that,
(a) Speed, 
Mass of the electron, 
Mass of the proton, 
The wavelength of the electron is given by :
The wavelength of the proton is given by :
(b) Kinetic energy, 
The relation between the kinetic energy and the wavelength is given by :
Hence, this is the required solution.
Answer:
c)wind
Explanation:
Wind from the given choices will have the greatest amount of kinetic energy.
Kinetic energy is the energy due to motion of a body. It is different from the energy at rest in a body.
- Wind is air in motion.
- Wind energy is a form of kinetic energy in motion.
A book on a table, a slice of pizza and a person at the top of the stairs are all at rest and will possess potential energy.
The particle is an electron. The field slows down the electron without deflecting it. The direction of the electric field is <u>right.</u>
In physics, the motion of electrically charged particles gives rise to a field called an electric field. It is measured in force per unit charge.
This field applies force on other charged particles.
Particles bearing opposite charges attract each other while particles having similar charges repel each other in the field.
If a positive charge is placed in the field then the field line moves in an outward direction and for a negative charge, the direction of the lines is inward.
