SECTION - A

An electron and a proton are moving along the same direction with the same kinetic energy. They enter a uniform magnetic field acting perpendicular to their velocities. The dependence of radius of their paths on their masses is :

$r ∝ m$
$r ∝ {√{m}}$
$r ∝ \;{1}/{m}$
$r ∝ \;{1}/{{√{m}}}$

Solution:
