Chapter 19, Problem 101PP
Predict/Calculate Referring to Example 19-14 In this system, the charge q1 is at the origin, the charge q2 is at x = 0 and y = 0.500 m, and point 3 is at x = y = 0.500 m. Suppose that q1 = +2.90μC, but that q2 is increased to a value greater than +2 90 μC. As a result, do (a) Enet and (b) θ increase, decrease, or stay the same? Explain. If Enet = 1.66 × 105 N/C, find (c) q2 and (d) θ.

GIVEN: x-axis Positive charge Q is distributed uniformly along the positive y-axis between y=0 and y=ay. A negative point charge −q lies on the positive x-axis, a distance x from the origin. a=length.
EQUATION: f=kdQ/r^(2) where sin(t)= r= sqrt(x^(2)+y^(2)
QUESTION: Please explain how the integral is used within this equation, then calculate the x-component of the electric field produced by the charge distribution Q at points on the positive x-axis.
Two metal spheres, each of radius 2.6 cm, have a center-to-center separation of 2.8 m. Sphere 1 has a charge of +1.2 × 10-8 C; sphere 2
has a charge of -3.3 x 10-8 C. Assume that the separation is large enough for us to assume that the charge on each sphere is uniformly
distributed (the spheres do not affect each other). With V= 0 at infinity, calculate in volts (a) the potential at the point halfway
between their centers and the potential on the surface of (b) sphere 1 and (c) sphere 2.
