Lorentz force in the electric and magnetic field is:
Correct answer: D. F = q(E+vB)
- A. F = qv(E+B)
- B. F = qE(v+B)
- C. F = qvB
- D. F = q(E+vB)
Explanation
Option D is correct since the Lorentz force refers specifically to the formula for the magnetic force, with the total electromagnetic force.Options A and B are incorrect since both the formula does not follow the Lorentz force definition. Option C is incorrect since the F = qvB formula is obtained after the definition of magnetic field or cross product.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
