Coulomb Balance Lab Report

If one lesson in electrostatic forces doesn¡¦t cover Coulomb¡¦s law then you have been served a great injustice. Coulomb¡¦s law is one of the fundamental principles that one needs to know when comparing two points (i.e. Q1, Q2) that are separated by a distance of r. This law is represented with the equation:

Where K=1/4ƒàƒÕ0 and ƒÕ0 is the permitivity of free space (ƒÕ0 =8.85 * 10-12 C2/Nm2)

In addition, at a large distance such spheres, when conducting, should vary with the equation, 1/r2. Of course when the sphere are moved into closer proximity the charges then redistribute to minimize potential energy. If by chance the charge of the two spheres are the same, then they will repe

In addition, since the sphere is a conducting capacitor, the charge will be Q=CV. When this is isolated, the capacitance of the sphere can be established by the equation C=1/4ƒàƒÕ0a, where a is the radius of the sphere. When combined, they in turn produce a charge overall of the sphere determined by Q=CV=4ƒàƒÕ0aV.
