A) kinetic energy
B) angular momentum
C) linear momentum
D) speed
Correct Answer: C
Solution :
Force acting on particle due to magnetic field B is \[F=q\,\,\vec{v}\,\,\times \,\,\vec{B}\] ?..(i) and centripetal force is \[F=\frac{m{{v}^{2}}}{r}\] ?..(ii) From Eqs. (i) and (ii), we get \[B=\frac{mv}{rq}=\frac{linear\text{ }momentum}{charge}\]You need to login to perform this action.
