Question 1
9 May 2023 S2
23A current carrying circular loop of radius 'R' and current carrying long straight wire are placed in the same plane. and are the currents through circular loop and long straight wire respectively. The perpendicular distance between centre of the circular loop and wire is 'd'. The magnetic field at the centre of the loop will be zero when separation 'd' is equal toTap an option to check your answer.
