A vertically positioned charged disk of radius R contains a unfirom positive charge density sigma. A mass (M, +Q) is suspended from the rim of the disk by a string of length L. Answer the following.
a.) Find the expression for the angle theta made between the disk edge and the length L.
b.) If the disk's radius is now extened to infinity then the answer to (a) must increase. Prove or disprove.
