A charge q moves in a region where electric field and magnetic field both exist, then force on it is

Multiple Choice Options

  • A q(v⃗×B⃗)q(\vec{v}\times\vec{B})
  • B qE⃗+q(v⃗×B⃗)q\vec{E}+q(\vec{v}\times\vec{B})
  • C qE⃗+q(B⃗×v⃗)q\vec{E}+q(\vec{B}\times\vec{v})
  • D qB⃗+q(E⃗×v⃗)q\vec{B}+q(\vec{E}\times\vec{v})
