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.
