MHT CET Physics question
A uniform magnetic field acts at right angles to the direction of motion of electrons, as a result the electron moves in a circular path of radius 2 cm. If the speed of the electrons is doubled, then radius of the circular path will be
Answer: (C)
Solution
, so doubling the speed doubles the radius to 4 cm; 2 cm
