Answer 2

The incorrect statement is (b) "Electric lines of force are closed curves".

Explanation:

(A) Electric current is a scalar quantity. It has a particular direction. It moves in the opposite direction of electron. But it is not a vector quantity. This statement is correct.

(B) Electric lines of force are closed curves. It is false as it starts from positive charge and ends at negative charge. It cannot form a closed current. This statement is incorrect.

(C) Magnetic lines of induction are closed curves. It is correct. It is because magnetic monopoles does not exists.

(D) According to Faraday law, the change in magnetic field induces an electric current in a coil. It is correct.

So, the incorrect statement is (b) "Electric lines of force are closed curves". Hence, this is the required solution.
