A) a net repulsive force away from the conductor
B) a net torque acting upward perpendicular to the horizontal plane
C) a net torque acting downward normal to the horizontal plane
D) a net attractive force towards the conductor
Correct Answer: D
Solution :
\[{{\mathbf{F}}_{2}}=-{{\mathbf{F}}_{4}}\] \[{{\mathbf{F}}_{1}}=\frac{{{\mu }_{0}}{{I}_{1}}Il}{2\pi d}\] \[{{\mathbf{F}}_{2}}=\frac{{{\mu }_{0}}{{I}_{1}}Il}{2\pi (d+l)}\] \[{{\mathbf{F}}_{1}}>{{\mathbf{F}}_{3}}\] \[{{F}_{net}}={{F}_{1}}-{{F}_{3}}\] So, wire attract loop.You need to login to perform this action.
