When arc length and radius of the circle become equal then the angle subtended at the center of the circle will be:

Correct answer: B. π rad

  • A. 1 rad
  • B. π rad
  • C. 53.7o
  • D. All of these

Explanation

The angular displacement traced by the body is said to be one radian when the arc length is equal to the radius of the circle.< AOB = 1radian

About Simple Harmonic Motion

Simple harmonic motion is oscillation in which acceleration is directly proportional to displacement and directed toward the equilibrium position. Work includes displacement, velocity, acceleration, phase, period, frequency, amplitude and energy, with applications to springs and simple pendulums. The restoring force and the conditions for SHM distinguish it from general periodic motion.
