Question
A particle of charge q and mass $m$ is moving with a velocity $-v \hat{i}(v \neq 0)$ towards a large screen placed in the $Y-Z$ plane at a distance $d$. If there is a magnetic field $\vec{B}=B_0 \hat{k}$, the minimum value of $v$ for which the particle will not hit the screen is
Select the correct option:
A
$\frac{2 q d B_0}{m}$
B
$\frac{\text { qdB }_0}{3 m}$
C
$\frac{\mathrm{qdB}_0}{2 \mathrm{~m}}$
D
$\frac{\text { qdB }_0}{m}$
✓ Correct! Well done.
