• Four charges_ +q,−q,+2q, and −2q are assembled around a square with side length a as shown in the figure
• In a certain region of space the electric potential can be described by the equation
• The figure shows a metal fuel tank in the shape of a rectangular prism_ its base is a square with side a and height is h
• Two air-filled, parallel plate capacitors, C1=2
• Two capacitors, C1=2
• Two solid, neutral conducting spheres of radius r are connected by a conductor with length L−2r so that the centres of the spheres are a distance L apart
• Two very thin conducting, concentric spheres have radii R1 and R2 as shown in the figure
• We shall charge a capacitor from its initial potential difference V=Vi=0 to a final potential difference V=Vf
