In this experiment, to begin with (at t = 0, without any external force), the pointer is at a non-zero mark, say at + 5 units. Now we give some initial displacement and record the maximum displacement of each successive oscillation cycle with time. We evaluate the damping constant Ym from this data and compare with the actual damping constant Ya (when the pointer is at zero displacement att 0). You may consider in both cases the same constant current was there in the electromagnet. Which of the following statements is correct? Select one: None of these. Ya < Ym Ya=Ym- Ya Ym-
