Assertion: Basic difference between an electric line and magnetic line of force is that former is discontinuous and the latter is continuous or endless.
Reason: No electric lines of force exist inside a charged body but magnetic lines do exist inside a magnet.

Options

A. Both A and Rare Tuę and R is the correct explanation of A
B. Both A and R are true but R is NOT the correct explanation of A
C. A is true but R is false
D. A is false and R is true

Answer

A

Explanation

Let us consider an electric dipole. The electric lines of force exist outside only and not inside the dipole. Let us take a magnetic dipole.
The magnetic lines of force exist outside as well as inside the dipole.
So, it can be said that magnetic lines of force are continuous and electric lines of force are discontinuous
So assertion and reason both are true and reason explains the assertion too.
