Chapter 2, Problem 2.8P
A crude device for measuring charge consists of two small insulting spheres of radius a, one which is fixed in position The other is movable along the x axis and is subject to a restraining force, where k is a spring constant The uncharged spheres are centered x= 0 and x= d. the latter fixed lithe spheres ate given equal and opposite charges of Q/C. obtain the expression by which Q may be found as a function of r Determine the maximum charge that can be measured in terms of t0, k, and d. and state the separation of the spheres then What happens is a larger charge is applied?
