Question

When a charged particle moving with velocity $\vec{v}$ is subjected to a magnetic field of induction $\vec{B}$, the force on it is non-zero. This implies that(a) angle between $\vec{v}\ and\ \vec{B}$ is necessarily 90°(b) angle between $\vec{v}\ and\ \vec{B}$ can have any value other than 90°(c) angle between $\vec{v}\ and\ \vec{B}$ can have any value other than zero and 180°(d) angle between $\vec{v}\ and\ \vec{B}$ is either zero or 180°
