Three 2.50 uC charges are placed on tiny conducting spheres at the ends of 1.00 m-long strings that are connected at 120 angles as shown below. The magnitude, in N, of the tension in any one of the strings is
A long cylinder (radius = 3.0 cm) is filled with a nonconducting material which carries a uniform charge density of 1.3 uC/m3. Determine the electric flux through a spherical surface (radius = 2.0 cm) which has a point on the axis of the cylinder as its center.
Two infinite, uniformly charged, flat surfaces are mutually perpendicular. One of the sheets has a charge density of +60 pC/m2, and the other carries a charge density of 80 pC/m2. What is the magnitude of the electric field at any point not on either surface?
