A charge $q$ moves in a region where electric field and magnetic field both exist, then force on it is
A$q \overrightarrow{ E }+ q (\overrightarrow{ V } \times \overrightarrow{ B })$
B$q (\overrightarrow{ V } \times \overrightarrow{ B })$
C$q \overrightarrow{ E }+ q (\overrightarrow{ B } \times \overrightarrow{ V })$
D$q \overrightarrow{ B }+ q (\overrightarrow{ E } \times \overrightarrow{ V })$

A$q \overrightarrow{ E }+ q (\overrightarrow{ V } \times \overrightarrow{ B })$
a (a)Lorentz force is given by
$\overrightarrow F = \overrightarrow {{F_e}} + \overrightarrow {{F_m}} = q\overrightarrow E + q(\overrightarrow v \times \overrightarrow B ) = q[\overrightarrow E + (\overrightarrow v \times \overrightarrow B )]$

A long wire A carries a current of $10\, amp$. Another long wire $B$, Which is parallel to $A$ and separated by $0.1\,m$ from $A$, carries a current of $5\, amp$, in the opposite direction to that in $A$. what is the magnitude and nature of the force experienced per unit length of $B$ $({\mu _0} = 4\pi \times {10^{ - 7}}\,weber/amp{\rm{ - }}m)$
A proton with a kinetic energy of $2.0\,eV$ moves into a region of uniform magnetic field of magnitude $\frac{\pi}{2} \times 10^{-3}\,T$. The angle between the direction of magnetic field and velocity of proton is $60^{\circ}$. The pitch of the helical path taken by the proton is $..........cm$ (Take, mass of proton $=1.6 \times 10^{-27}\,kg$ and Charge on proton $=1.6 \times 10^{-19}\,kg)$
A galvanometer has a resistance of $20\,\Omega$ and reads full-scale when $0.2\, V$ is applied across it. To convert it into a $10\, A$ ammeter, the galvanometer coil should have a
Infinite number of straight wires each carrying current $I$ are equally placed as shown in the figure. Adjacent wires have current in opposite direction. Net magnetic field at point $P$ is
A proton and an alpha particle of the same enter in a uniform magnetic field which is acting perpendicular to their direction of motion. The ratio of the circular paths described by the alpha particle and proton is ....
