PHY 2049 Study Guide - Midterm Guide: Electric Field, Net Force
Document Summary
The figure shows two unequal point charges, q and q, of opposite sign. Charge q has greater magnitude than charge q. Two-point charges q 1 and q 2 of equal magnitudes and opposite signs are positioned as shown in the figure. Three equal negative point charges are placed at three of the corners of a square of side d as shown in the figure. Coulomb"s law for the magnitude of the force f between two particles with charges q and q separated by a distance d is. |f|=k|qq |d2, where k=14 0, and 0=8. 854 10 12c2/(n m2) is the permittivity of free space. Consider two point charges located on the x axis: one charge, q1 = -17. 5 nc , is located at x1 = -1. 710 m ; the second charge, q2 = 40. 0 nc , is at the origin (x=0. 0000). To understand coulomb"s law, electric fields, and the connection between the electric field and the electric force.
