A charged particle is moving with velocity $\vec{v}$ in a magnetic field of induction $\vec{B}$. The force on the particle will be maximum when:
  • (a)$\vec{v}$ and $\vec{B}$ are at an angle of $45^\circ$.
  • (b)$\vec{v}$ and $\vec{B}$ are perpendicular.
  • (c)$\vec{v}$ and $\vec{B}$ are in the same direction i.e., at an angle of $0^\circ$.
  • (d)$\vec{v}$ and $\vec{B}$ are in opposite directions i.e., at an angle of $180^\circ$.
