Get started for freeFind the net force on a \(2.0-C\) charge at the origin of an \(x y\) -coordinate system if there is a \(+5.0-C\) charge at \((3 \mathrm{~m}, 0)\) and \(a-3.0-C\) charge at \((0,4 \mathrm{~m})\)
Two charged spheres are \(8 \mathrm{~cm}\) apart. They are moved closer to each other enough that the force on each of them increases four times. How far apart are they now?
When a metal plate is given a positive charge, which of the following is taking place? a) Protons (positive charges) are transferred to the plate from another object. b) Electrons (negative charges) are transferred from the plate to another object. c) Electrons (negative charges) are transferred from the plate to another object, and protons (positive charges) are also transferred to the plate from another object. d) It depends on whether the object conveying the charge is a conductor or an insulator.
How many electrons are required to yield a total charge of 1.00 C?
Performing an experiment similar to Millikan's oil drop experiment, a student measures these charge magnitudes: \(3.26 \cdot 10^{-19} \mathrm{C} \quad 5.09 \cdot 10^{-19} \mathrm{C} \quad 1.53 \cdot 10^{-19} \mathrm{C}\) \(6.39 \cdot 10^{-19} \mathrm{C} \quad 4.66 \cdot 10^{-19} \mathrm{C}\) Find the charge on the electron using these measurements.
