Question
An electron having mass $9 \times 10^{-31} \mathrm{~kg}$, charge $1.6 \times 10^{-19} \mathrm{C}$ and moving with a velocity of $10^{6} \mathrm{~m} / \mathrm{s}$ enters a region where mag. field exists. If it describes a circle of radius $0.10 \mathrm{~m}$, the intensity of magnetic field must be Tesla(a) $1.8 \times 10^{-4}$(b) $5.6 \times \overline{10^{-5}}$(c) $14.4 \times 10^{-5}$(d) $1.3 \times 10^{-6}$
Step 1
Step 1: The magnetic force acting on the electron is given by the equation $F = qvB$, where $q$ is the charge of the electron, $v$ is the velocity of the electron, and $B$ is the magnetic field. Show more…

An electron moving with velocity of $10^{6} \mathrm{~m} / \mathrm{s}$ enters a region where magnetic field exists. If it describes a circle of radius $0.10 \mathrm{~m}$, the intensity of the magnetic field must be: (a) $1.8 \times 10^{-4} \mathrm{~T}$ (b) $5.6 \times 10^{-5} \mathrm{~T}$ (c) $14.4 \times 10^{-5} \mathrm{~T}$ (d) $1.3 \times 10^{-6} \mathrm{~T}$
An electron moves with a speed of $2 \times 10^{5} \mathrm{~m} / \mathrm{s}$ along the $+x$ -direction in a magnetic field $\vec{B}=(\hat{i}-4 \hat{j}-3 \vec{k})$ tesla. The magnitude of the force (in newton) experienced by the electron is (the charge on electron $=1.6 \times 10^{-19} \mathrm{C}$ ) (a) $1.18 \times 10^{-13}$ (b) $1.28 \times 10^{-13}$ (c) $1.6 \times 10^{-13}$ (d) $1.72 \times 10^{-13}$
An electric field of intensity $6 \times 10^{4} \mathrm{Vm}^{-1}$ is applied perpendicular to the direction of motion of the electron. A magnetic field of induction $8 \times 10^{-2} \mathrm{Wm}^{-2}$ is applied perpendicular to both the electric field and direction of motion of the electron. What is the velocity of the electron if it passes undeflected? (a) $7.5 \times 10^{5} \mathrm{~ms}^{-1}$ (b) $7.5 \times 10^{-5} \mathrm{~ms}^{-1}$ (c) $48 \times 10^{-2} \mathrm{~ms}^{-1}$ (d) It is never possible
