The determination of the value of acceleration due to gravity (g) by simple pendulum method employs the formula,
$$g=4\pi^2\frac{L}{T^2}$$
The expression for the relative error in the value of 'g' is:
1.  $$\frac{\Delta g}{g}=\frac{\Delta L}{L}+2\Big(\frac{\Delta T}{T}\Big)$$
2.  $$\frac{\Delta g}{g}=4\pi^2\Big[\frac{\Delta L}{L}-2\frac{\Delta T}{T}\Big]$$
3.  $$\frac{\Delta g}{g}=4\pi^2\Big[\frac{\Delta L}{L}+2\frac{\Delta T}{T}\Big]$$
4.  $$\frac{\Delta g}{g}=\frac{\Delta L}{L}-2\Big(\frac{\Delta T}{T}\Big)$$
