- In a thundercloud, there may be electric charges of +40.0 C near the top of the cloud and 40.0 C near the bottom of the cloud. These charges are separated by 2.00 km. What is the electric force on the top charge?In your own words, describe the difference between the terms gravitational force and gravitational field.What is the difference between a contact force and a field force? List all the forces presented in Chapters 1 through 22. Which are field forces? Which are contact forces? Which forces are macroscopic manifestations of the electromagnetic force? What does that tell you about contact forces? Explain your answers.
- Which of the following statements are true statements about electric force? Choose all that apply. Electric force is a contact force. Electric forces can only act between charged objects - either like-charged or oppositely-charged. Electric forces between two charged objects increases with increasing separation distance. Electric forces between two charged objects increases with increasing quantity of charge on the objects. If object A attracts object B with an electric force, then the attractive force must be mutual - i.e., object B also attracts object A with the same force. A doubling of the quantity of charge on one of the objects results in a doubling of the electric force. A tripling of the quantity of charge on both of the objects results in an increase in the electric force by a factor of 6. A doubling of the separation distance between two point charges results in a quadrupling of the electric force. A tripling of the separation distance between two point charges results in…Let there be three charges whose locations are given with respect to a coordinate system - Charge q1 = 42 µCis located at P1 (0, -24) Charge 18 µCis located at P2 (15, –37.5)and Charge q3 = 6 µCis located at P3 (25,0).
