A long solid cylindrical conductor of radius R is carrying a constant current I. The variation of magnetic field due to this conductor is given by.
`B={:{((KIr)/(R^(2)),,r le R),((KI)/(r),,r gt R):}`
Here k is a constant and r = distance between the axis of the conductor and the point at which magnetic field is given.
Which of the following plots is correct regarding the magnitude of magnetic field B with distance r?
