- Two small pith balls, each of mass m = 18.1 g, are suspended from the ceiling of the physics lab by 0.7 m long fine strings and are not moving. If the angle which each string makes with the vertical is 0 = 36.4°, and charges on the two balls are equal, what is the magnitude of that charge (in µC)? (Please note that the unit of charge is micro-Coulomb here - some browsers might not display the Greek letter mu correctly and show as an m.)Common transparent adhesive tape becomes charged when pulled from a dispenser. If one piece is placed above another, the repulsive force can be great enough to support the top piece's weight. Assuming equal point charges as an approximation, calculate the magnitude of each charge, in coulombs, if the electrostatic force is great enough to support the weight of a 0.35 mg piece of tape held 0.85 cm above another. 91. In the figure, point A is a distance L away from a point charge Q. Point B is a distance 4L away from Q. What is the ratio of the electric field at B to that at A, Es/EA? B A -3L

In that field, what is the magnitude of the electrostatic force on (a) an electron and (b) an ion with a single electron missing?Two red blood cells each have a mass of 9.05 x 10-¹4 kg and carry a negative charge spread uniformly over their surfaces. The repulsion arising from the excess charge prevents the cells from clumping together. One cell carries -3.00 pC and the other -2.90 pC, and each cell can be modeled as a sphere 3.75 x 10-6 m in radius. If the red blood cells start very far apart and move directly toward each other with the same speed, what initial speed would each need so that they get close enough to just barely touch? Assume that there is no viscous drag from any of the surrounding liquid. initial speed: What is the maximum acceleration of the cells as they move toward each other and just barely touch? maximum acceleration: m/s m/s²A small sphere is electrically neutral before 2.4 x 1011 electrons are added to it.
