(a) Draw the schematic sketch of a cyclotron. Explain the shape of the path on which charged particle moves when the particle is accelerated by it.
(b) To convert a given galvanometer into a voltmeter of ranges 2 V, V and volt, resistances and ohm respectively, are required to be connected in series with the galvanometer. Obtain the relationship between and .
a) Cyclotron is a device that works on the principle that the kinetic energy of a charged particle increases when the charged particle moves in a crossed oscillating electric and magnetic field
.
Each time, the acceleration increases the energy of the particle. As the energy increases, the radius of the circular path increases. So, the path is spiral.
b)
