A force F cos (! t) is applied to a spring of negligible mass which is fixed on one end and on the other end has an attached mass m = 1 kg. The spring constant is k = 100 N/m. If the applied force remains constant in magnitude, the amplitude of oscillation of the mass on the spring is maximum when the fre- quency of the applied force (cycles per second) is about
