What is the answer of question number 13 and also provide the formula if possible.
Dear student,
The answer to this is D) None of these
This is because the formula for magnetic field B when a current I passes through a straight conductor is
B = μoI / (2πr)
where r is the distance of point P where we want to calculate the magnetic field from the straight conductor.
