Suppose you find a star which has helium fusion in the core surrounded by a shell of hydrogen fusion. What is supporting the structure of the stellar core against the relentless force of gravity

Which two particles are found in the center of an atom

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?

How much work would it take to move a coulomb charge across a 4 volt potential difference?
