Answer in units of N.(a) What is the electric field of an oxygen nucleus at a point that is 10−10 m from the nucleus?

- How much work is done by the Coulomb force when the alpha particle moves to the midpoint of one of the sides of the square?Alpha particles (having charges of 2e and masses of 6.64x10−27 kg) were fired toward a gold nucleus with charge 79e (you do not need to account for the electrons). An alpha particle, initially very far from the gold nucleus, is fired at 5.70x107 m/s directly toward the nucleus, as in the figure. (b) How close does the alpha particle get to the gold nucleus before turning around? (Assume the gold nucleus remains stationary.) Alpha particles (having charges of 2e and masses of 6.64x10−27 kg) were fired toward a gold nucleus with charge 79e (you do not need to account for the electrons).

- Solar wind is a flow of heavily charged ions emanating from the Sun's corona. Spectroscopic analysis suggests it contains a density of approximately 5.0 electrons per cubic centimeter (cm³). Given that the elementary charge e x 1.6 × 10-19 C and using the combined average of your measured values of Q, determine the charge density of a cubic meter (m3) of solar wind sample as a function of Q.Supposing that an electron in a hydrogen atom ispositioned at an average distance of 5.29x10–11 m from the nucleus (so called Bohr radius of the atom), determine the Coulomb force of attraction between the electron and the proton (that is, the hydrogen atom nucleus at the center of the atom). The electron charge is –1.6x10–19 C, the proton charge is +1.6x10–19 C.A typical AA size rechargeable NiMH battery can store 1100-2100 mAh of electric charge. The small print on the battery in your hand says 1530 mAh. Can you express this amount of electric charge using the usual coulomb units? You are now charging a camera battery. The charger moves 4470 C of electric charge from the negative terminal of the battery to the positive terminal. (In reality the charger moves the negative electrons from the positive terminal to the negative terminal, but this is not important for us right now.) Assuming - incorrectly - that the voltage of the battery remains a constant 3.20 V during the whole charging process, determine the work done by the charger. And now you are charging a capacitor bank for a high-voltage physics experiment. The power supply moves Q = 8990 C of electric charge in the charging process. The supply is set to stop, when the voltage reaches AV = 710 V. How much work did the power supply perform?

Calculate the force of electric repulsion or attraction between the α particles and compare them with gravitational force of attraction between themA nucleus of oxygen contains 8 protons. (a) Calculate the electric force it would exert on an electron situated at a distance of 60 pm (=60×10-12 m), and the acceleration with which the electron would move. (b) Since the nucleus of oxygen has radius 2.8 fm (= 2.8×10-15 m), calculate the average charge density associated with a nucleus of oxygen. You now pack 1012 nuclei of oxygen into a spherical volume of radius 1.0 m. (c) Calculate the electric field generated by such charge distribution at a distance of 2.0 m from the center.
