A charge q moves with velocity

{ }^{\prime} \vec{V}{ }^{\prime}

through electric field

(\overrightarrow{\mathbf{E}})

as well as magnetic field

(\overrightarrow{\mathbf{B}})

. Then the force acting on it is

View answer and explanation

Correct option: B

\mathrm{q} \overrightarrow{\mathrm{E}}+\mathrm{q}(\overrightarrow{\mathrm{V}} \times \overrightarrow{\mathrm{B}})

Option B (

\mathrm{q} \overrightarrow{\mathrm{E}}+\mathrm{q}(\overrightarrow{\mathrm{V}} \times \overrightarrow{\mathrm{B}})

) is correct because it represents the Lorentz force, which is the sum of the electric and magnetic forces on a charge.
