- The figure shows 3 positive pointcharges, at the corners of a square. Thethave Determine the magnitude and direction öf the total electric field at the center of the Square expression for Q =1.0 n Coul and a = l,Ocm, labeled B. Evaluate your Symbolic B.You drop your smartphone and crack the battery. As the lithium-ion components start to mix, the phone is charged to uniform surface charge density o. Using the given dimensions, Determine the electric field vector at a point P, which is a distance d above the center of the clock. O W h P 0The classic Millikan oil drop experiment was the first to obtain an accurate measurement of the charge on an electron. In it, oil drops were suspended against the gravitational force by a vertical electric field. 1a. Given the oil drop to be 0.99 μm in radius and have a density of 910 kg/m3: Find the weight of the drop. 1b.If the drop has a single excess electron, find the electric field strength needed to balance its weight. This is not and will not be graded
- A charge of 22.2 pC is distributed uniformly on a spherical surface (r1 = 2.0 cm), and a second charge of-9.2 pC is distributed uniformly on a concentric thin spherical surface (r2 = 4.0 cm).
