Assertion When a charge is brought near a conductor then a very small value current is established in the conductor Reason since electric field inside the conductor has to be zero so to overcome the electric field of the external charge, internal charge of conductor is collected all accross the surface.
- A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
- B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
- C. Assertion is correct but Reason is incorrect
- D. Both Assertion and Reason are incorrect
Step-by-step solution
When an external charge is brought near a conductor, free electrons within the conductor move to neutralize the external field inside, causing a transient current. The reason correctly states that the internal electric field must be zero, which is achieved by charge redistribution on the surface. This redistribution motion constitutes the current. Thus, both statements are correct, and the reason correctly explains why the current occurs.
