The magnetic field between the plates of radius 12 cm separated by distance of 4 mm of a parallel plate capacitor of capacitance \[100\text{ }pF\] along the axis of plates having conduction current of \[0.15A\] is
A)zero
B)\[1.5\,T\]
C)\[15\,T\]
D)\[0.15\,T\]
Correct Answer:
A
Solution :
[a] As \[B\propto r\], since the point is on the axis where r=0, So B=0
