The distance covered by a particle undergoing SHM in one time period is ( amplitude = A )

Options

  1. Azero
  2. BA
  3. C2 ~A
  4. D4 ~A

Correct answer

D. 4 ~A

Step-by-step solution

In a simple harmonic motion (SHM) the particle oscillates about its mean position on a straight line. The particle moves from its mean position (O) to an extreme position ( P ) and then return to its mean position covering same distance of A. Then by the conservative force, it is moved in opposite direction to a point Q by distance A and then back to mean position covering a distance of A. This comprises of one time period as shown below Hence, in one time period it covers a distance of x = OP + PO + OQ + QO = A +
