4.Moving Charges and Magnetism
medium
Statement $-1$ : Path of the charge particle may be straight line in uniform magnetic field.
Statement $-2$ : Path of the charge particle is decided by the angle between its velocity and the magnetic force working on it
A
Statement$-1$ is true, Statement$-2$ is true; Statement$-2$ is not the correct explanation of Statement$-1.$
B
Statement$-1$ is false, Statement$-2$ is true.
C
Statement$-1$ is true, Statement$-2$ is false.
D
Statement$-1$ is true, Statement$-2$ is true; Statement$-2$ is the correct explanation of Statement$-1.$
Solution
Path of the charge particle is decided by angle $b/w\,\,v\,\,\&\,\,B$
$\mathrm{F}=\mathrm{q}(\vec {\mathrm{V}} \times \vec {\mathrm{B}})$
$\mathrm{F}=\mathrm{q} v \mathrm{B} \sin \theta$
