A chronograph is to be operated by a 2-s pendulum of length L shown in Fig. P2.1

Question

A chronograph is to be operated by a 2-s pendulum of length L shown in Fig. P2.12. A platinum wire attached to the bob competes the electric timin circuit through a drop of mercury as it swings through the lowest point. (a) What should be the length L of the pendulum? (b) If the platinum wire is in contact with the mercury for 0.3175 cm of the swing, what must be the amplitude to limit the duration of contact 0.01 s? (Assume that the velocity during contact is constant and that the amplitude of oscillation is small.)
