Question

A particle having the same charge as of electron moves in a circular path of radius 0.5 cm under the influence of a magnetic field of 0.5 T . If an electric field of $100 \mathrm{~V} / \mathrm{m}$ makes it to move in a straight path, then the mass of the particle is (Given charge of electron $=1.6 \times 10^{-19} \mathrm{C}$ )

Select the correct option:

$9.1 \times 10^{-31} \mathrm{~kg}$

$1.6 \times 10^{-27} \mathrm{~kg}$

$1.6 \times 10^{-19} \mathrm{~kg}$

$2.0 \times 10^{-24} \mathrm{~kg}$
