Aclosely wound search coil has an area of 3.20 cm2, 120 turns, and a resistance of 60.0 æ. it is connected to a charge-measuring instrument whose resistance is 45.0 æ. when the coil is rotated quickly from a position parallel to a uniform magnetic field to a position perpendicular to the field, the instrument indicates a charge of 3.56 * 10-5 c. what is the magnitude of the field?

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?
