If (T = 2pi sqrt{frac{l}{g}}), make g the subject of the formula
- A.
(4π l^{2}) / T - B.
(4π^{2}l) / T^{2} - C.
(4π^{2}l^{2}) / T^{2} - D.
(2π√l) / T
Correct Answer: Option B
Explanation
(T = 2pi sqrt{frac{l}{g}})
(frac{T}{2pi} = sqrt{frac{l}{g}})
((frac{T}{2pi})^{2} = frac{l}{g})
(therefore g = frac{4 pi^{2} l}{T^{2}})
