Extracted text: needs complete detailing. take N=70 b=20 a) The figure shows an oscillatory system where the mass 'M' is required to remain stationary even if an oscillatory force "Fo cos ot" acts on this mass 'M’. This mass 'M’ is a part of a simple harmonic system of stiffness 'k' and also connected to mass 'm' by a spring of stiffness 's'. If all oscillations are along the x-axis, find the value of frequency 'o' with which the small mass 'm' should oscillate to keep the mass 'M' stationary? Consider the following numerical values for calculations: M=100 kg, Fo cos ot m k=5 N/m, m='B’ kg, s='N' N/m
