Which one of the following expressions represents the total force F⃗\vec F acting on a charge qq moving with velocity v⃗\vec v in the simultaneous presence of uniform electric field E⃗\vec E and magnetic field B⃗\vec B? (a) F⃗=q (E⃗+B⃗×v⃗)\vec F = q\,(\vec E + \vec B \times \vec v) (b) F⃗=q (v⃗×B⃗)\vec F = q\,(\vec v \times \vec B) (c) F⃗=q (E⃗+v⃗×B⃗)\vec F = q\,(\vec E + \vec v \times \vec B) (d) F⃗=q (E⃗−v⃗×B⃗)\vec F = q\,(\vec E - \vec v \times \vec B)
