Question

An electron is projected at right angle to a uniform magnetic field (B) with
velocity v. Derive the expression for the radius of circular path described by the
electron. Take 'm' as mass of electron and 'e' its electric charge.
​

Answer 1

Explanation:

the electro negetavity have posutive charge it have magnitude field with velocity v then expression for the radius of circular path described by the electon is the circular path of the object .

the take m as mass of electon is negetavily charged and e is its electrical energy is having positive energy
