Two parallel plates 10 cm on a side are given equal and opposite charges of magnitude C The plates are 1.5 mm apart. What is the electric field at the center of the region between the plates?
Two thin parallel conducting plates are placed 2.0 cm apart. Each plate is 2.0 cm on a side; one plate carries a net charge of µC and the other plate carries a net charge of µC.
What is the charge density on the inside surface of each plate?
What is the magnitude of the electric field between the plates?
The figure shows a small sphere of mass 0.25 g that carries a charge of C. The sphere is attached to one end of a very thin silk string 5.0 cm long. The other end of the string is attached to a large vertical conducting plate that has a charge density of C/m2. What is the angle that the string makes with the vertical?
