Questions
A uniform magnetic field acts 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 electrons is doubled, then the radius of the circular path will be
detailed solution
Correct option is C
r=mvqB or r∝vAs v is doubled, the radius also becomes double. Hence radius = 2x2= 4cm.Talk to our academic expert!
