A. Consider a charge Q fixed in place at the origin that creates an electric field in the surrounding region. We call a charge w

hich gives rise to the electric field the source charge. You bring a small charge q from infinite distance to a distance r from the source charge adiabatically, that is, infinitely slowly such that the electric field due to the source charge is not disturbed. This small charge q is called a test charge. Now answer the following questions. All of your answers will be in terms of q, Q, r and the dielectric constant εo, as appropriate and be careful about your signs. 1. What is the electric potential energy of the charge q as a function of the distance r away from

Answer:

U = k Q q / r

Explanation:

The potential electric energy for a point charge is

       U = k q₁ q₂ / r

Where k is the Coulomb constant, q are the electric charges and r is the distance between them

Let's replace our values

     U = k Q q / r

Note that the positive power is because the two charges have the same sign, so we have to do a job to move the test load and also a scalar

A transparent oil with index of refraction 1.28 spills on the surface of water (index of refraction 1.33), producing a maximum o
Ad libitum [116K]

Answer:

The thickness of the oil slick is 1.95\times10^{-7}\ m

Explanation:

Given that,

Index of refraction = 1.28

Wave length = 500 nm

Order m = 1

We need to calculate the thickness of oil slick

Using formula of thickness

2nt= m\lambda

Where, n = Index of refraction

t = thickness

\lambda = wavelength

Put the value into the formula

2\times1.28 \times t=1\times\times500\times10^{-9}

t = \dfrac{1\times\times500\times10^{-9}}{2\times1.28 }

t=1.95\times10^{-7}\ m

Hence, The thickness of the oil slick is 1.95\times10^{-7}\ m

4. How does a molecule differ from an atom
tia_tia [17]

Answer:

Explanation:

In a molecule, atoms are bonded together by single, double, or triple bonds. An atom has a nucleus surrounded by electrons. ... So another difference between atoms and molecules is that when similar atoms combine together in varying numbers, molecules of different properties can be formed.
