In an experiment there is an attraction of a charged object to the wall. Depicts the microscopic level mechanism for this observation. Identify the correct statements that apply when the object is positively charged.

1.How far are the two charges if their magnitudes are 70 µC and 90 µC and is acted by 100 N force between them? 2. What is the magnitude of electrical force of attraction between an iron nucleus (26 protons) and its innermost electron if the distance between them is 1.0x10^-12 N 3. What formula do we use to find the value of an unknown charge with the same magnitude? show the manipulation starting from the coulomb's law  formula

When you remove your wool suit from the dry cleaner’s garment bag, the bag becomes positively charged. Explain how this occurs.

Two +1 C charges are separated by 3000 m. a). Draw a sketch of the scenario and b) Determine the magnitude of the electric force between them?

Students noted that their friend's hair standing up when he removed the hat from the head. Their science teacher asked them to explain the reason based on your electrostatics knowledge. Which will be the best answer? O A. There is thermal energy produced and that caused kinetic energy to the hair. O B. Chemical reactions make the hair more rigid. O C. Hair gains electrons when the hat is removed and so hair is attracted to the surrounding air. D. The hair loses electrons causing the them to repel each other. Same charges repel.

Describe the difference in the electric field direction between positive and negative charged particle.

Write the letter corresponding to your correct answer.

8. Which one of these statements is true? A. Like charges attract, unlike charges repel. B. Like charges attract, like charges repel. C. Unlike charges attract, unlike charges repel. D. Unlike charges attract, like charges repel.

A charged plastic rod attracts a charged glass rod. This means that______________.     a. one of them is negatively charged and the other is positively charged. b.one of them is positively charged and the other is positively charged. c. one of them is negatively charged and the other is negatively charged. d. one of them is negatively charged and the other is neutrally charged.
