Q: A body is said to move with Simple Harmonic Motion, if its acceleration is.................
  • A. Always directed away from the centre, at the point of reference
  • B. Proportional to square of the distance from the point of reference
  • C. Proportional to the distance from the point of reference and direction towards it
  • D. None of these
Correct Answer: Option C - In general, a body is said is move or vibrate with simple harmonic motion, if it satisfies the following two conditions– (a) Its acceleration is always directed toward the centre, known as point of reference on mean position. (b) Its acceleration is proportion to the distance from that point.
C. In general, a body is said is move or vibrate with simple harmonic motion, if it satisfies the following two conditions– (a) Its acceleration is always directed toward the centre, known as point of reference on mean position. (b) Its acceleration is proportion to the distance from that point.
