I need all answers please, this is for practice for my exam.

Electrostatic Fields, Potential and Forces- Concepts and Equations- SHOW ALL WORK! 13. Placed exactly between two oppositely charged point charges, a test charge (the sensor) will show zero/minimum maximum force (N) or field strength (N/C). 14. The point charges used in the simulation are .0x10" C g ano ou smb . If two such positive charges are placed 2.0 m away from cach other, the force between them would be... (use formula) SHOW WORK HERE: 15. What is the magnitude of the electric field produced 2.0m away from one of the charges? WORK HERE 16. A test charge of4.5 C in a field of strength 2.2,N/C would feel what force? WORK 17. What is the value of the electric field when a -9.6 V potential is found 1.4 m from its center? WORK 18. What is the electrostatic potential found.68 m from the center of a 2.3 Vm field? WORK 19. A balloon is electrostatically charged with 3.4 must sou soubs of charge. A second balloon 23 cm away is charged with 5.1 HC of charge. The force of attraction/repulsion between the two charges will be: WORK 20. If one of the balloons has a mass of 0.084 kg, with what acceleration does it move toward or away from the other balloon? WORK q1 42 21. Look at the two charges above. 3 10° C and q8 x 10 C, what is the direction of the electric field at point x? To the right of the page To the top of the page To the left of the page To the bottom of the page 22. How many electrons would have to be transferred off a neutral object for it to have a positive charge of 4.48 micxCaulombs. -10 Cy?

Explanation / Answer

You should know the guidelines before posting so many questions....

13) minimum

14) F = kq1q2/r2

F = 9e9*1e-9*1e-9 / 4

F = 2.25e-9 N

15) doesn't make any sense...from one charge...if so then

E = kq/r2

16) F = qE

F = 4.5*2.2

F = 9.9 N

17 ) E = V/d

E = 9.6/1.4 = .857 V/m

18) V = 0.68*2.3

V = 1.564 V
