9:17 AM stillman.instructure.com DQuestion 18 4 pts If the size of the charge value is tripled for both of the two point charges maintained at a constant separation, the mutual force between them will be changed by what factor? O 0.33 D Question 19 4 pts The beam of electrons that hits the screen of an oscilloscope is moved up and down by O gravity O a phosphorescent coating the electron gun O The electrical charges on deflecting plates DQuestion 20 4 pts Current is the rate of flow of - per unit time. O voltage O charge O neutrons O none of the above

Explanation / Answer

Question 18) F = Q1Q2/r²

If size of charges are tripled then force will become 9 times.

Question 19) The beam of electrons that hits the screen of an oscilloscope is moved up and down by the electrical charges on deflecting plates.

Question 20) current is the rate of flow of charge per unit time.
