Figure shows a uniform magnetic field of induction B confined to a cylindrical volume of radius R. B is increasing at a constant rate of 100 T/s. What is instantaneous acceleration experienced by a charged particle placed at C distant r from centre. Assume r = 5 m. (Given (q)/(m) = 1.6 xx10^(-2) C/kg)

Answer»

Solution :`E= (R )/(2) (dB)/(dt)`
Force EXPERIENCED by an ELECTRON `ma =F =eF = (ER)/(2) (dB)/(dt) or a = ( e)/(m)xx(r )/(2) (dB)/(dt) = 4 m//s^(2)`
