NEETPhysicsElectrostatics
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : If a positive point charge is brought near an isolated neutral metal cube, the cube becomes negatively charged. Reason (R) : If a positive point charge is brought near an isolated neutral metal cube, the cube remains neutral. In the light of the above statements, choose the most appropriate answer
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
B. Both (A) and (R) are true and (R) is NOT the correct explanation of (A).
Step-by-step solution
Assertion (A): If a positive point charge is brought near an isolated neutral metal cube, the cube becomes negatively charged. - This statement is true. When a positive charge is brought near the neutral metal cube, it induces a separation of charges within the cube. The electrons in the cube are attracted toward the positive charge, resulting in the side of the cube nearest to the charge becoming negatively charged. The other side will have a positive charge, but overall, the cube will still be neutral in terms of
