Question

When a charged particle moving with velocity overset arrow v is subjected to a magnetic field of induction overset arrow B , the force on it is non-zero. This implies that (A) angle between overset arrow v and overset arrow B is either zero or 180o (B) angle between overset arrow v and overset arrow B is necessarily 90o (C) angle between overset arrow v and overset arrow B can have any value other than 90o (D) angle between overset arrow v and overset arrow B can have any value other than zero and 180o

∵ F=qvBsin θ F=0 , if θ =0o or 180o

Q. When a charged particle moving with velocity $v \to$ is subjected to a magnetic field of induction $B \to$ , the force on it is non-zero. This implies that

angle between $v \to$ and $B \to$ is either zero or $18 0^{o}$

angle between $v \to$ and $B \to$ is necessarily $9 0^{o}$

angle between $v \to$ and $B \to$ can have any value other than $9 0^{o}$

angle between $v \to$ and $B \to$ can have any value other than zero and $18 0^{o}$

$∵$ $F = q v B s in θ$
$F = 0$ , if $θ = 0^{o}$ or $18 0^{o}$

Q. When a charged particle moving with velocity v→ is subjected to a magnetic field of induction B→ , the force on it is non-zero. This implies that

angle between v→ and B→ is either zero or 180o

angle between v→ and B→ is necessarily 90o

angle between v→ and B→ can have any value other than 90o

angle between v→ and B→ can have any value other than zero and 180o
