Question

What is the formula for electric force on a charge in an electric field?

Options

• \[\vec F=q\vec E\]

• \[\vec F=q(\vec v\times\vec B)\]

• \[F=qvB\sin\theta\]

• \[F=BIl\]

Answer 1

Electric force is the product of charge and electric field: \[\vec F=q\vec E\]. It is distinct from the magnetic-force term involving velocity and magnetic field.
