| ASSERTION: No net force acts on a rectangular coil carrying a steady current when suspended freely in a uniform magnetic field. |
| REASON: Forces acting on each pair of the opposite sides of the coil are equal and opposite. |
A) If both assertion and reason are true and reason is the correct explanation of assertion.
B) If both assertion and reason are true and reason is not the correct explanation of assertion.
C) If assertion is true but reason is false.
D) If both assertion and reason are false.
E) If assertion is false but reason is true.
Correct Answer: A
Solution :
In a rectangular coil carrying a steady current, the direction of current in opposite side of coil is opposite to each other, therefore, force acting on each pair of the opposite sides of the coil are equal and opposite, i.e. net force on the coil is equal to zero.
