# A student uses a pendulum to determine the acceleration due to gravity, \( g \). They measure the pendulum’s length \( L \) and its period \( T \). Which equation should they use to calculate \( g \)?

A student uses a pendulum to determine the acceleration due to gravity, \( g \). They measure the pendulum’s length \( L \) and its period \( T \). Which equation should they use to calculate \( g \)?

- **A.** \[ g = \frac{1}{L} \left( \frac{2\pi}{T} \right)^{2} \]
- **B.** \[ g = 2\pi \sqrt{ \frac{L}{T} } \]
- **C.** \[ g = L \left( \frac{T}{2\pi} \right)^{2} \]
- **D.** \[ g = L \left( \frac{2\pi}{T} \right)^{2} \]
