**6 A bead with mass 1.8 × 10-² kg is moving along a wire in the positive direction of an x axis. Beginning at time t = 0, when the bead passes through x = 0 with speed 12 m/s, a constant force acts on the bead. Figure 7-24 indicates the bead's position at these four times: to = 0, t = 1.0 s, t2 = 2.0 s, and tz = 3.0 s. The bead momentarily stops at t = 3.0 s. What is the kinetic energy of the bead at t = 10 s? %3D 12 5 10 15 20 x (m)

Coulomb’s Law

Coulomb's law states that the attraction or repulsion force between two charged things is proportional to the product of their charges and inversely proportional to the square of their distance. It has an effect along the line that connects the two-point charges.
