P114 - PROBLEM SET 1 Homework to be handed in by 1800 hours on Tuesday 30 January 2007 . [1] Electric and gravitational forces. a) What would be the proton’s mass if the gravitational force between two protons at rest were to equal the electric force? How does this compare with its actual mass? b) What would be the electric force between two dimes (each of mass 2gm) placed at opposite ends of a 10 meter lecture table if their nuclear and electronic charges were unbalanced by 1%. Can you think of some object whose “weight“ equals that force? [2] A 2 × 10 6 C charge is at the center of a cube of side 20 cm. What is the electric fl ux through one of the faces of the cube? [3] Four charges of equal magnitude, | q | = 2 × 10 18 C, are arranged at the four corners of a square of side L = 5 cm as shown in the fi gure. Calculate the magnitude, in Newtons, and the direction of the force acting on the lower-left corner charge due to the presence of the other charges.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
