# Mass hangs in equilibrium on a spring Watch

1. Here is the question:
A mass M hangs in equilibrium on a spring. M is made to oscillate about the equilibrium position by pulling it down 10 cm and releasing it. The time for M to travel back to the equilibrium position for the first time is 0.5s. Which line, A to D, is correct for these oscillations?
A) Amplitude(cm) 10 , Period(s) 1.0
B) Amplitude(cm) 10 , Period(s) 2.0
C) Amplitude(cm) 20, Period(s) 2.0
D) Amplitude(cm) 20, Period(s) 1.0

Not sure which formula to use or how to go about answering the question. An explanation would be appreciated. As always, thanks
