Acircuit is constructed with four resistors, one inductor, one battery and a switch as shown. the values for the resistors are: r1 = r2 = 47 ω, r3 = 116 ω and r4 = 127 ω. the inductance is l = 380 mh and the battery voltage is v = 24 v.

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
