Answer to relevant QuestionsA positively charged rod is brought close to a neutral piece of paper, which it attracts, Draw a diagram showing the separation of charge and explain why attraction occurs.The form of Coulomb’s law is very similar to that for Newton’s law of universal gravitation. What are the differences between these two laws? Compare also gravitational mass and electric charge?What is the repulsive electrical force between two protons 5.0 X 10-15 m apart from each other in an atomic nucleus?Particles of charge + 75 + 48, and –85μC are placed in a line (Fig. 16-49). The center one is 0.35 m from each of the others. Calculate the net force on each charge due to the other two. Two small non-conducting spheres have a total charge of 90.0μC. (a) When placed 1.06m apart, the force each exerts on the other is 12.0N and is repulsive. What is the charge on each? (b) What if the force were ...
