The electric potential in a region that is within 2.00 mm of the origin of a rectangular coordinate system is given by V=Axl+Bym+Czn+DV=Axl+Bym+Czn+D, where AA, BB, CC, DD, ll, mm, and nn are constants. The units of AA, BB, CC, and DD are such that if xx, yy, and zz are in meters, then VV is in volts. You measure VV and each component of the electric field at four points and obtain these results: What is VV at the point (0, 0, 0)? What is the magnitude of EE at the point (0, 0, 0)? What is VV at the point (0.50 mm, 0.50 mm, 0.50 mm)? What is the magnitude of EE at the point (0.50 mm, 0.50 mm, 0.50 mm)? What is VV at the point (1.00 mm, 1.00 mm, 1.00 mm)? What is the magnitude of EE at the point (1.00 mm, 1.00 mm, 1.00 mm)?
