A beam of charged particles of charge q and a mass m are accelerated from rest through a potential difference of 100V. They pass through crossed electric and magnetic fileds which together produce null deflection .If these electronic and magnetic fields are respectively 15xx10^(3)Vm^(-1)and 5Wbm^(-2) ,then q/m has a value, in C kg^(-1) ,equal to

A proton when accelerated through a potential difference of V, has a De-Broglie wavelength lambda associated with it.if an alpha -particle is to have the same De-Broglie wavelength lambda, it must be accelerated through a potential difference of

(a) Estimate the speed with which electrons emitted from a heated emitter of an evacuated tube impinge on the collector maintained at a potential difference of 500 V with respect to the emitter. Ignore the small initial speeds of the electrons. The specific charge of the electron, i.e., its e/m is given to be 1.76 xx 10^(11) C kg^(-1) . (b) Use the same formula you employ in (a) to obtain electron speed for an collector potential of 10 MV. Do you see what is wrong ? In what way is the formula to be modified?
