Magnetic Effects Of Current Question 382

Question: In an experiment, electrons are accelerated, from rest, by applying a voltage of 500 V. Calculate the radius (in metre) of the path if a magnetic field 100 mT is then applied. [Charge of the electron $ =1.6\times {{10}^{-19}}C $ Mass of the electron $ ~=9.1\times {{10}^{-31}}kg] $

Solution:

Answer: $ (7.5\times {{10}^{-4}}) $
