A pendulum oscillates simple harmonically if and only if (1) the size of the bob of pendulum is negligible in comparison with the length of the pendulum (II) the angular amplitude is less than 10° is Option(a)Both(l) and (II) are correct.

Explaination:

  • The angular displacement of a pendulum is represented by the equation θ = 0.32*cos(ωt) where θ is in radians and ω = 4.43 rad/s.
