Question

STATEMENT - 1 : A uniformly distributed direct current flows through a solid long metallic cylinder along its length. It produces magnetic field only outside the cylinder .
STATEMENT - 2 : A thin long cylindrical tube carrying uniformly distributed direct current along its length does not produce a magnetic field inside it.Moreover, a solid cylinder can be supposed to be made up of many thin cylindrical tubes.

• A. Statement-1 is True, Statement-2 is True; Statement-2 is a correct explanation for Statement-1.
• B. Statement-1 is True, Statement-2 is True; Statement-2 is NOT a correct explanation for Statement-1
• C. Statement-1 is True, Statement-2 is False
• D. Statement-1 is False, Statement-2 is True

Answer 1

Answer: (D)

Statement-1 is False, Statement-2 is True

Statement-1:
A uniformly distributed direct current flows through a solid long metallic cylinder along its length. It produces magnetic field both outside and inside the cylinder.
Statement-2:
A thin long cylindrical tube carrying uniformly distributed direct current along its length does not produce a magnetic field inside it.Moreover, a solid cylinder can be supposed to be made up of many thin cylindrical tubes.
