A) Experiences a net force only.
B) Experiences a torque only.
C) May undergo translatory motion as well as rotational motion.
D) remains at absolute rest.
Correct Answer: C
Solution :
The magnetic field due to wire At N-pole \[{{B}_{1}}=\frac{{{\mu }_{0}}i}{2\pi a}\otimes \] At S- pole \[{{B}_{2}}=\frac{{{\mu }_{0}}i}{2\pi b}\otimes \] Force exerted at N-pole. \[{{F}_{1}}=n{{B}_{1}}\] Similarly at S-pole, \[{{F}_{2}}=m{{B}_{2}}\] Since, \[{{B}_{1}}>{{B}_{2}}\] \[\therefore \] \[{{F}_{2}}<{{F}_{1}}\] \[\Rightarrow \] System has net force. Similarly, net torque exists on system.You need to login to perform this action.
