Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R):

 Assertion (A): Self-inductance is called the inertia of electricity. Reason (R): It is on account of self-inductance that the coil opposes any change in current passing through it.

In the light of the above statements choose the correct answer from the options given below:

 1 Both (A) and (R) are true and (R) is the correct explanation of (A). 2 Both (A) and (R) are true but (R) is not the correct explanation of (A). 3 (A) is true but (R) is false. 4 Both (A) and (R) are false.

Given below are two statements:
 Statement I: The magnetic field due to a very long current-carrying solenoid, at its centre, is inversely proportional to the radius of the solenoid, other things remaining constant. Statement II: The magnetic energy stored in a solenoid carrying a current $$I$$ is directly proportional to $$I^2.$$

 1 Statement I is incorrect and Statement II is correct. 2 Both Statement I and Statement II are correct. 3 Both Statement I and Statement II are incorrect. 4 Statement I is correct and Statement II is incorrect.
