The sextant (or perhaps "quadrant" would be more correct) consists
of a right angled frame subtended by a protractor, similar to a normal sextant. At the end of each arm of the right angled frame is a mass held by a spring in a slider. Both of the sliders are parallel to one of the arms, as illustrated below: Oriented so that the plane of the sextant contains the center of the field source, rotate the sextant until the displacements of the masses in the two sliders are equal, and then sight the field source on a line through the corner of the frame, and mark the angle on the protractor. The angle "theta" between the line of sight and the slider direction is related to the exponent c in the force law according to the equation tan^2(theta) + (c+1)tan(theta) - c = 0 For example, if the angle reads 29.3165 degrees, then |
