QAIPM-2011-Ph-1832: NEET 2011 Physics - Class 12 AIPM-2011-Ph-1832 Solution: A square loop carrying a steady current I is placed in a…
A square loop carrying a steady current I is placed in a horizontal plane near a long straight conductor carrying a steady current at a distance d from the conductor as shown in figure. The loop will experience a net attractive force towards the conductor a net repulsive force away from the conductor a net torque acting upward perpendicular to the horizontal plane a net torque acting downward normal to horizontal plane
Multiple Choice Options
- A 0.65 eV
- B 1.9 eV
- C 11.1 eV
- D 13.6 eV
Step-by-Step Verified Solution
E n = _ 13.6 n 2
_ E 1 = �13.6 eV
E 2 = �3.4 eV
E 3 = �1.5 eV
E 4 = �0.85 eV
_ E 3
� E 2
= �1.5 � (�3.4) = 1.9 eV
E 4
� E 3
= �0.85 � (�1.5) = 0.65 eV
Obviously, difference of 11.1 eV is not
possible.
