Q # 2
Assume that a proton has a mass of 3.34 × 10-27Kg and a charge of +e. It travels in a circular path with a radius 6.96mm in a magnetic field with magnitude 2.50T.
a) Find the time required for it to make half a revolution.
b) Find the speed of the proton.
c) Through what potential difference would the proton have to be accelerated to acquire this speed? Marks = 10
Q # 3
What is your opinion about the radio signals and light waves? Is there any difference between them or a same thing? Justify it. Marks = 5

ReplyDeleteidea for the solution of Q1 AND Q3
FOR Q1 current always moves from higher potential to lower potential this is because the energy of the system needs to be minimized. The direction of current flow is opposite to the direction of flow of current. So electron moves from lower potential to higher potential
FOR Q3
Electromagnetic waves are produced by accelerating charges. The fields of the wave are self-supporting - the electric field induces the magnetic field, and the magnetic field induces the electric field. Both radio waves and light are electromagnetic waves; their main difference is their frequency. Radio waves are created by the acceleration of electrons in a radio antenna, and light waves are created by the oscillations of the electrons within atoms. The electromagnetic wave has two components: the electric radiation field and the magnetic radiation field.
The magnitude of the electric radiation field is directly proportional to the acceleration, and it is inversely proportional to the radial distance from the accelerating chargE
