Multiple electrostatics questions.

Understand the Problem

The image contains a series of multiple-choice questions related to physics concepts, particularly electrostatics. These questions cover topics such as electric force, electric fields, charge distribution, and safety during lightning storms. They require an understanding of fundamental principles of electromagnetism to select the correct answer.

Answer

Here are the answers: 1. B 2. A 3. E 4. D 5. B 6. A 7. A 8. A 9. D 10. B 11. A, C, E 12. A 13. E

Here are the answers to the multiple-choice questions:

(b) It is attractive and directed in the -x direction.
(a) It does not change.
(e) They are attracted to each other by the same amount.
(d) The field at point 1 is larger, because the field lines are closer together in that region.
(b) The field points toward the positive charge, and the force on the negative charge is in the opposite direction to the field.
(a) decreases.
(a) remain almost exactly the same.
(a) greater than
(d) most everyday objects have as many plus charges as minus charges.
(b) inside a metal car.
(a), (c), and (e) are the worst places in MisConceptual Question 10.
(a)
(e) negative or neutral.

More Information

These answers are based on standard principles of electrostatics, such as Coulomb's Law, electric fields, and charging mechanisms.

Tips

Carefully consider the definitions and relationships between charge, force, and electric fields to avoid mistakes.
