Physics · JEE | Moving Charges and Magnetism

The electric force on a point charge \( q \) in an electric field \( \vec{E} \) combined with magnetic force in magnetic field \( \vec{B} \) is expressed by the Lorentz force equation as:

1. A
   \( \vec{F} = q\vec{E} + q(\vec{B} \times \vec{v}) \)
2. B
   \( \vec{F} = q(\vec{E} - \vec{v} \times \vec{B}) \)
3. C
   \( \vec{F} = q(\vec{E} + \vec{v} \times \vec{B}) \)
4. D
   \( \vec{F} = q\vec{v} \times (\vec{E} + \vec{B}) \)
