An electron revolves along a circular path on a plane perpendicular to a uniform magnetic field of 0.001 T with a velocity of `10^(6)m.s^(-1)`. (i) What is the force acting on the electron? (ii) What is the radius of its circular path? (iii) For each complete revolution of the electron what will be the increase of its energy? Given, charge of an electron `=-1.6xx10^(-1)C` mass `=9.1xx10^(-31)kg`.

Explanation

`1.6xx10^(-16)N` , (ii) 5.7 mm, (iii) 0
