The image above represents gravity anomaly for an infinitely long cylinder.

To compute for gravity anomaly for an infinitely long cylinder, five essential parameters are needed and these parameters are **Gravitational Constant (G), Anomalous Density (Δρ), Radius of Cylinder (b), Depth Buried (d) **and **Horizontal Distance (x).**

The formula for calculating gravity anomaly for an infinitely long cylinder:

δg_{x} = ^{GΔρ2πb²d} / _{x² + d²}

Where:

δg_{x} = Gravity Anomaly for an Infinitely Long Cylinder

G = Gravitational Constant

Δρ = Anomalous Density

b = Radius of Cylinder

d = Depth Buried

x = Horizontal Distance

Let’s solve an example;

Find the gravity anomaly for an infinitely long cylinder when the gravitational constant is 6.67E-11, the anomalous density is 9, the radius of cylinder is 11, the depth buried is 8 and the horizontal distance is 10.

This implies that;

G = Gravitational Constant = 6.67E-11

Δρ = Anomalous Density = 9

b = Radius of Cylinder = 11

d = Depth Buried = 8

x = Horizontal Distance = 10

δg_{x} = ^{GΔρ2πb²d} / _{x² + d²}

δg_{x} = ^{6.67e-11(9)2π(11)²(8)} / _{(10)² + (8)²}

δg_{x} = ^{6.67e-11(9)2π(121)(8)} / _{(100) + (64)}

δg_{x} = ^{6.67e-11(9)(6082.123)} / _{164}

δg_{x} = ^{0.000003651098} / _{164}

δg_{x} = 2.226e-8

Therefore, the **gravity anomaly for an infinitely long cylinder **is **2.226e-8 mGal.**
