Problem

A particle having the same charge as of electron moves in a circular path of radius

0.5 \text{ cm}

under the influence of a magnetic field of

0.5 \text{ T}

. If an electric field of

100 \text{ V/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} \text{ C}

) a.

9.1 \times 10^{-31} \text{ kg}

1.6 \times 10^{-27} \text{ kg}

1.6 \times 10^{-19} \text{ kg}

2.0 \times 10^{-24} \text{ kg}
