Description
Summary:THE term average radial gravity ḡ ( r ) may be defined as the arithmetic mean of all the gravity values lying on the circumference of a circle of radius r . A similar definition holds good in the magnetic case also. This can be represented as a series expansion in terms of the even vertical derivatives at the centre as: where a 2 , a 4 , a 6 ,… are closely connected with the even vertical derivatives at the centre by the relations: and a 0 approximates the gravity value at the centre.
