There is a single electron at a distance from the point charge. On which of the following quantities does the force on the electron depend? Check all that apply. For the same situation as in Part A, on which of the following quantities does the electric field at the electron's position depend?

Two identical 82 mg dust particles very far apart (pee 0) are moving directly toward each other at a speed of 3698 m/s. the charge on each is-719 ? c. determine how close they will get to each other. let k = 9x109 n-m2/c2 & ignore gravity.

Arunner is training for an upcoming marathon by running around a 100-m-diameter circular track at constant speed. let a coordinate system have its origin at the center of the circle with the x-axis pointing east and the y-axis north. the runner starts at (x, y) = (50 m, 0 m) and runs 2.5 times around the track in a clockwise direction.

What is the coefficient of kinetic friction μk between the block and the tabletop?
