Which one of the following represents simple harmonic motion?(a) Accel

1.	Which one of the following represents simple harmonic motion?(a) Acceleration = kx(b) Acceleration = k0 x+k1 x^2(c) Acceleration = -k(x+a)(d) Acceleration = k(x+a)
Answer» Correct answer is (c) Acceleration = -k(x+a) To explain: Acceleration = -kX, X = x+a Thus the acceleration is proportional to displacement and acts in its opposite direction. Hence, acceleration = -k(x+a) represents simple harmonic motion.
