Document Summary

Assume the distance between the third charge and q1 is x, and the charge of the third q is positive. F x = 0 kqq1 x2 kqq2 (x + 4)2. We saw that if we assume a test charge of q is located near a charge of q, a force of f q will act on it as. Electric field is a vector field, or a vector function. It has a magnitude and direction which is, in general, a function of space (position x,y,z) and time (t) as shown in fig. F (x, y, z; t) y (2, 2. 5, 0) x. Figure 3. 1: the electric field of a charge point lies at (2, 2. 5, 0)
