Q. The magnetic field between the plates of radius 12 cm separated by distance of 4 mm of a parallel plate capacitor of capacitance 100 pF along the axis of plates having conduction current of 0.15 A is
A) Zero
B) 1.5 T
C) 15 T
D) 0.15 T
Explanation
(a) As $B \propto r$, since the point is on the axis, where $r = 0$, so $B = 0$
