Coulomb's Law

Coulomb's Law: Force Between Two Points

The force between two point charges is given by F = (k(q_1)(q_2))/r^2 k = 9.0 * 10^9 * (N * M)/C^2 Using Coulomb's Law, What is the force, in billions of Newtons, rounded to the nearest whole number, between a pair of like charged particles if one particle is 2.0 Culomb and the second particle is 2.0 Culomb and they ar

Describe all aspects of the motion fully.

An ά-particle, with mass of the proton and charge q=2e is shot with speed 8 x 10^6 m/s at an angle of 25 degree to an x-directed magnetic field B = 0.20 T. Describe all aspects of the motion fully.

Coulomb's Law and Two Point Charges

Two point charges have a total charge of 590 uC. When placed 1.30 m apart, the force each exerts on the other is 22.8 N and is repulsive. What is the charge on each?

Orbital Box Diagram and Notations

Compare the elements B, Al, C, and Si. a) Which has the most metallic character? b) Which has the largest atomic radius? c) Which has the most negative electron affinity? d) Place the three elements B, Al, and C in order of increasing first ionization energy. Using an orbital box diagram and the noble gas notation

Magnitude of net force

Three positive particles of charges Q = 61.8 micro coulombs are located at the corners of an equilateral triangle with a side L = 16.3cm. Calculate the magnitude of the net force on each particle.

Magnetic Field - In a circular region of radius r1 there is a uniform magnetic field coming out of the page and decreasing at a constant rate dB/dt = -K. A circular wire loop of radius r2 lies entirely outside the magnetic field region. In what direction does the conventional current I flow in the loop? What is the magnitude of I? Draw the induced (non-Coulomb) electric field in the loop. What is its magnitude?

Magnetism is reinforced.

1. Why is a chunk of iron attracted to either pole of a magnet? What does this tell you about the reliability of attraction as a test of whether something is permanently magnetized or not? A classic puzzle involves two seemingly identical rods, one steel and magnetized (with poles at its ends), the other soft iron and not magnet

Electrostatics: Forces

Problem 1. Determine the electric force acting on an electron placed in a uniform north-to-south E-field of 8.0 x 10^4 N/C in vacuum. 2. A +10-uC test-charge at some point beyond a charged sphere experiences an attractive force of 40 uN. Please coompute the value of the E-field of the sphere at that point in a vacuum. 3

Bainbridge Mass Spectrometer

This problem has to do with the fact that one of Dalton's original Atomic Theory postulates was not true. 1) One gram equivalent weight of Lithium is 6.941 grams, according to chemical reaction analysis. What does this statement mean? If the valence of Lithium is known to be +1, what is the gram atomic weight of Lithium? So
