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?

- A 3-phase, 4-wire distributor supplies a balanced voltage of 400/230 V to a load consisting of 8 A at p.f. 0.7
lagging for R-phase, 10 A at p.f. 0-8 leading for Y phase and 12 A at unity p.f. for B phase. The resistance
of each line conductor is 0.4 2. The reactance of neutral is 0.2 2. Calculate the neutral current, the supply
voltage for R phase and draw the phasor diagram. The phase sequence is RYB.
