Question

Please do both problems and explain steps

Chapter 18, Problem 10 2 Your answer is partially correct. Try again. Two tiny conducting spheres are identical and carry charges of -16.2HC and +61.0fHC. They are separated by a distance of 3.74 cm. (a) What is the magnitude of the force that each sphere experiences? (b) The spheres are brought into contact and then separated to a distance of 3.74 cm. Determine the magnitude of the force that each sphere now experiences (a) Number :Units N (b) Number units N Click if you would like to Show Work for this question: Open Show Work

Answer 1

After contact charges equality distributed on both the spheres

(a) F = k q_1 q_2/r^2 F = (9 times 10^9) (16.2 times 10^- 6) (61 times 10^- 6)/0.0374)^2 F = 6.36 times 10^3 N (Attractive) (b) After contact q_1 = q_2 = 61 - 16.2/2 = 22.4 mc F = (9 times 10^9) (22.4 times 10^- 6)^2/(0.0374)^2 F = 3.23 times 10^3 N (Attractive)
