The Hydrogen Atom The electron and proton of a hydrogen atom are separated (on the average) by a distance of approximately 5.3 x 10-11 m. Find the magnitudes of the electric force and the gravitational force between the two particles. SOLUTION Conceptualize Think about the two particles separated by the very small distance given in the problem statement. In the chapter entitled Universal Gravitation, we found the gravitational force between small objects to be weak, so we expect the gravitational force between the electron and proton to be significantly --Select--- than the electric force. Categorize The electric and gravitational forces will be evaluated from universal force laws, so we categorize this example as -Select- problem. Use Coulomb's law to find the magnitude of the electric force (in N): Fe-ke jell-el 2 Use Newton's law of universal gravitation and the table of particle masses to find the magnitude of the gravitational force (in N): m_m F₂ = Gem N Finalize The ratio 2 x 10 Therefore, the gravitational force between charged atomic particles is negligible when compared with the electric force. Notice the similar forms of Newton's law of universal gravitation and Coulomb's law of electric forces. Other than magnitude, what is a fundamental difference between the two forces? EXERCISE Hint N Two identical objects each hold a net charge of q = 7e. If the gravitational force between the two objects exactly cancels the electrostatic force between the objects, what is the mass of each object (in kg)? kg

Magnetic Field Of Coaxial Cable

The word coaxial means same axis. So for a long straight cable to be coaxial, it must have concentric cylindrical shaped conductor around it. Coaxial cable (popularly called ‘coax’) has various applications ranging from current conductors to radiofrequency signal transmitters. This cable has lower emission losses and provides protection from electromagnetic interference which allows signals with less power to transmit over longer distances.For example, currents produced in the pickup of a stereo turntable generally travel to the amplifier through a coaxial cable.The self-inductance of a coaxial cable is another important characteristic, because it influences the propagation of electrical signals in the cable.
