One may simplify further by introducing expression for q from the electrostatic force equation and may do more arithmetic For my point here, this much is enough, it is clear that dq/dt depends on dx/dt (it is vivid in the question too). Two metal spheres A and B are suspended from two silk threads and a positively charged glass rod is held near A, as shown in diagram. In this lab, the pith ball electroscope consists of two small balls (the pith balls) suspended by threads, as shown in Figure 3a. given to the inner sphere.

(2) If the spheres are losing charge, the repulsive Coulomb force decreases and thus also the distance x decreases. 2003-2023 Chegg Inc. All rights reserved. Physics, 6th Edition Chapter 23. If the charges have the same sign, the Coulomb force is repulsive, separating the balls a distance \r" away from each . Bob Pursley isn't at his computer right now but I don't think he would mind if I explained that ADDING an electron to a non-metal makes it become negatively charged. After bringing them in contact with each other, they again placed at the same distance apart. A. It only takes a minute to sign up.
