Directions (Q. Nos. 1-11): In the following questions, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as. |
Assertion (A): Magnetic field interacts with a moving charge only. |
Reason (R): Moving charge produces a magnetic field. |
A) Both A and R are true 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
Correct Answer: A
Solution :
Option [a] is correct. Explanation: Current carrying wire creates magnetic field. This magnetic field has no effect on a stationary charge. But when the charge also moves, it creates a current. This current produces a magnetic field. Two fields interact and the charge is deflected. So, the assertion is true. Moving charge creates a current which produces a magnetic field. So, the reason is also true. Reason is the correct explanation of A.You need to login to perform this action.
