Finite Line of Charge: Two Thin 80

question 24

Essay

Finite line of charge: Two thin 80.0-cm rods are oriented at right angles to each other. Each rod has one end at the origin of the coordinates, and one of them extends along the +x-axis while the other extends along the +y-axis. The rod along the +x-axis carries a charge of -15.0 µC distributed uniformly along its length, and the other rod carries +15.0 µC uniformly over its length. Find the magnitude and direction of the net electrical force that these two rods exert on an electron located at the point (40.0 cm, 40.0 cm). (e = 1.60 × 10^-19 C, ε₀ = 8.85 × 10^-12 C²/N ∙ m²)

Gastrulation

A phase early in the embryonic development of most animals, during which the single-layered blastula is reorganized into a multilayered structure known as the gastrula.

Germ Layers

The three primary layers of cells (ectoderm, mesoderm, and endoderm) in the early embryo that give rise to all organs and tissues in the body.

Embryonic Disk

Point in the inner cell mass at which the embryo begins to be formed.

Ectoderm

Outermost of the three germ layers of an embryo.
