Two particles of masses $m_{a} a n d m_{b}$ and same charge are projected in a perpendicular magnetic field. They travel along circular paths of radius $r_{a} a n d r_{b}$ such that $r_{a} > r_{b} .$ Then which of the following is true?

Options:

Answer:

Solution:

Radius of circular path $r_{a} = \frac{m_{a} v_{a}}{q B}$

And $r_{b} = \frac{m_{b} v_{b}}{q B}$

According to question

$r_{a} > r_{b}$

$\frac{m_{a} v_{a}}{q B} > \frac{m_{b} v_{b}}{q B}$

or $m_{a} v_{a} > m_{b} v_{b}$
