NEETPhysicsElectrostatics
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : Any arbitrary displacement of charges inside a conducting shell does not introduce any change in the electrostatic field of the outer space. Reason (R) : A closed conducting shell divides the entire space into the inner and outer parts which are completely independent of one another in respect of
Options
- ABoth (A) and (R) are true and (R) is the correct explanation of (A).
- BBoth (A) and (R) are true and (R) is NOT the correct explanation of (A).
- C(A) is true but (R) is false.
- D(A) is false but (R) is true.
Correct answer
A. Both (A) and (R) are true and (R) is the correct explanation of (A).
Step-by-step solution
Assertion (A): Any arbitrary displacement of charges inside a conducting shell does not introduce any change in the electrostatic field of the outer space. - This statement is true. Inside a conductor, the electric field is zero, and any redistribution of charge within a conducting shell does not affect the electric field outside the shell. The outer field remains unchanged as long as there are no external influences. Reason (R): A closed conducting shell divides the entire space into the inner and outer parts, whi
