Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : A small body suspended by a light spring performing SHM. When the entire system is immersed in a non-viscous liquid period of oscillating does not change. Reason (R) : In simple harmonic motion the acceleration is always in a direction opposite to that of the displacement from mean position. In th

Options

  1. ABoth (A) and (R) are true and (R) is the correct explanation of (A).
  2. BBoth (A) and (R) are true and (R) is NOT the correct explanation of (A).
  3. C(A) is true but (R) is false.
  4. 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).
