Questions
An electron accelerated through a potential difference y enters into a uniform transverse magnetic field and experiences a force F. If the accelerating potential increases to 2V, the electron in the same magnetic field will experience a force :
detailed solution
Correct option is C
12mv2=eV or V=(2eV/m)1/2Force F =evB=eB(2eV/m)1/2 or F∝VWhen V is doubled, then F' = 2⋅FTalk to our academic expert!
