### What are some examples of problems and solutions from the book?

To give you an idea of what kind of problems and solutions you can find in solucionario de joseph edminister 49, here are some examples from different parts of the book:

PART I: ELEMENTS OF VECTOR CALCULUS

Chapter 1: Vector Analysis

Section 1.1: Scalar And Vector Fields

Problem #1:

Given two scalar fields f(x,y,z) = x^2 + y^2 + z^2 and g(x,y,z) = x + y + z find: (a) The gradient of f at point P(1,-1,-1) (b) The gradient of g at point P(1,-1,-1) (c) The directional derivative of f along g at point P(1,-1,-1) Solution #1:

(a) The gradient of f at point P(1,-1,-1) is given by: grad f = (df/dx)i + (df/dy)j + (df/dz)k where i,j,k are unit vectors along x,y,z axes respectively. To find df/dx , df/dy , df/dz , we need to take partial derivatives of f with respect to x,y,z respectively: df/dx = (d/dx)(x^2 + y^2 + z^2) = 2x df/dy = (d/dy)(x^2 + y^2 + z^2) = 2y df/dz = (d/dz)(x^2 + y^2 + z^2) = 2z Therefore, grad f = (2 x)i + (2y)j + (2z)k At point P(1,-1,-1), we have x = 1, y = -1, z = -1. Therefore, grad f = (2*1)i + (2*-1)j + (2*-1)k grad f = 2i - 2j - 2k This is the gradient of f at point P(1,-1,-1). (b) The gradient of g at point P(1,-1,-1) is given by: grad g = (dg/dx)i + (dg/dy)j + (dg/dz)k where i,j,k are unit vectors along x,y,z axes respectively. To find dg/dx , dg/dy , dg/dz , we need to take partial derivatives of g with respect to x,y,z respectively: dg/dx = (d/dx)(x + y + z) = 1 dg/dy = (d/dy)(x + y + z) = 1 dg/dz = (d/dz)(x + y + z) = 1 Therefore, grad g = (1)i + (1)j + (1)k grad g = i + j + k This is the gradient of g at point P(1,-1,-1). (c) The directional derivative of f along g at point P(1,-1,-1) is given by: Df(P,g) = grad f(P) . u where u is the unit vector in the direction of g. To find u, we need to normalize g by dividing it by its magnitude: u = g / g g = sqrt(g . g) g = sqrt((x + y + z)^2) g = sqrt((1 - 1 - 1)^2) g = sqrt(9) g = 3 Therefore, u = g / g u = (i + j + k) / 3 u = (1/3)i + (1/3)j + (1/3)k This is the unit vector in the direction of g. Now, we can find Df(P,g) by taking the dot product of grad f(P) and u: Df(P,g) = grad f(P) . u Df(P,g) = (2i - 2j - 2k) . ((1/3)i + (1/3)j + (1/3)k) Df(P,g) = (2/3)i . i - (2/3)i . j - (2/3)i . k - (2/3)j . i + (2/3)j . j + (2/3)j . k - (2/3)k . i - (2/3)k . j + (2/3)k . k Df(P,g) = (2/3)(i . i) - (2/3)(i . j) - (2/3)(i . k) - (2/3)(j . i) + (2/3)(j . j) + (2/3)(j . k) - (2/3)(k . i) - (2/3)(k . j) + (2/3)(k . k) Df(P,g) = (2/3)(1) - (2/3)(0) - (2/3)(0) - (2/3)(0) + (2/3)(1) + (2/3)(0) - (2/3)(0) - (2/3)(0) + + Df(P,g) = 4/3 This is the directional derivative of f along g at point P(1,-1,-1). PART II: ELECTROSTATICS

Chapter 4: Electric Potential

Section 4.4: Capacitance

Problem #10:

A parallel-plate capacitor has a capacitance of 10 pF and a plate area of 100 cm^2. The plates are separated by a distance of d cm. Find: (a) The value of d (b) The charge on each plate when a potential difference of 100 V is applied across the capacitor (c) The energy stored in the capacitor Solution #10:

(a) The value of d can be found by using the formula for capacitance of a parallel-plate capacitor: C = epsilon_0 * A / d where C is the capacitance, epsilon_0 is the permittivity of free space, A is the plate area, and d is the plate separation. Rearranging for d, we get: d = epsilon_0 * A / C Plugging in the given values, we get: d = 8.85 * 10^-12 * 100 * 10^-4 / 10 * 10^-12 d = 8.85 * 10^-4 m d = 0.885 mm This is the value of d. (b) The charge on each plate when a potential difference of 100 V is applied across the capacitor can be found by using the formula for charge-voltage relation of a capacitor: Q = C * V where Q is the charge, C is the capacitance, and V is the potential difference. Plugging in the given values, we get: Q = 10 * 10^-12 * 100 Q = 10^-9 C Q = 1 nC This is the charge on each plate. (c) The energy stored in the capacitor can be found by using the formula for energy of a capacitor: W = Q^2 / 2C where W is the energy, Q is the charge, and C is the capacitance. Plugging in the given values, we get: W = (10^-9)^2 / 2 * 10 * 10^-12 W = 5 * 10^-7 J W = 0.5 microJ This is the energy stored in the capacitor.
