0.4 Electric Force and Charge

Last updated 14 days ago

5 questions

Our textbook for this summer assignment will be OpenStax College Physics for AP Courses. Please study sections 18.1, 18.2, and 18.44 in the book, and then do Problems 25-27, 36 and 6 in the "Problems and Exercises" section for Chapter 18. Put your answers below. If you format your answers correctly, formative will auto-grade when you submit the assignment. Include units on all answers, with a space before the unit. For instance, "27.4 km/s". Express large and small numbers in scientific notation with the letter e: "4.5e13 kg".

Required

25.(a) How strong is the attractive force between a glass rod with a 0.700μC charge and a silk cloth with a –0.600μC charge, which are 12.0 cm apart, using the approximation that they act like point charges? (to three decimal places)

Required

26.Two point charges exert a 5.00 N force on each other. What will the force become if the distance between them is increased by a factor of three? (to three decimal places)

Required

27.Two point charges are brought closer together, increasing the force between them by a factor of 25. By what factor was their separation decreased?

Required

36.At what distance is the electrostatic force between two protons equal to the weight of one proton? (in meters, to three decimal places)
