A parallel plate capacitor of capacitance 10microfarads has the space between filled with material with
(dielectric constant k)= 4.0. The capacitor is charged to a potential difference of 2.0V . With the capacitor connected
to the battery the dielectric is removed.
1. The capacitance is F...
a) Three pithballs are suspended from thin threads.Various objects are then rubbed against other
objects (nylon against silk, glass against polyester, etc.) and each of the pithballs is charged by
touching them with one of these objects. It is found that pithballs 1 and 2 attract each other...
