The electric force is much stronger than the gravitational force
so we can often neglect gravity in electricity and magnetism. How
far does the electron of a hydrogen atom have to be removed from
the nucleus (contains only one proton) for the force of attraction
equal the weight of the electron at the surface of the Earth (g=9.8
m/s2)? Is that large compared to the size of an atom?

It is known that the electric force of repulsion between two electrons is much stronger than the gravitational attraction. For two electrons at a distance d apart, calculate the ratio of the size of the electrostatic repulsion to that of the gravitational attraction at a disance d apart, calculate the ratio of the size of the electrostatic repulsion to that of the gravitational attraction Use the following data: k-8.99x 109 Nm2/C2, e-1.60x10-19 C, G-6.67x10-11 Nm2/kg2, me 9.11x10-31 kg.

It is known that the electric force of repulsion between two electrons is much stronger than the gravitational attraction. For two electrons at a distance d apart, calculate the ratio of the size of the electrostatic repulsion to that of the gravitational attraction. Use the following data: k = 8.99×109 Nm2/C2, e = 1.60×10-19 C, G = 6.67×10-11 Nm2/kg2, me = 9.11×10-31 kg.

In 1959 Lyttleton and Bondi suggested that the expansion of the Universe could be ex plained on the basis of Newtonian mechanics if matter carried a net electric charge. Imagine a spherical volume, V, of astronomical size containing unionized atomic hydrogen of uniform number density n- NH/V, where N is the total number of hydrogen atoms, and assume that the proton charge is qp (1 +η) q , where q is the electron charge. So, η tells us how different...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
