A charge q moves in a region where electric field \(\vec{E}\) and magnetic field \(\text { E }\) both exist, then the force on it is:

\(q \vec{v} \times \vec{E}\)
\(q \vec{E}+q(\vec{v} \times \vec{E})\)
\(q \overrightarrow{\mathrm{~B}}+q \overrightarrow{\mathrm{E}} \times \overrightarrow{\mathrm{v}}\)
\(q \vec{E}+q(\vec{E} \times \vec{v})\)

Answer

(B) q E +q( v E )
