Equations e = 1 2πε0 qd z3 and e = 1 2πε0 p z3 are approximations of the magnitude of the electric field of an electric dipole, at points along the dipole axis. consider a point p on that axis at distance z = 4.50d from the dipole center (where d is the separation distance between the particles of the dipole). let eappr be the magnitude of the field at point p as approximated by e = 1 2πε0 qd z3 and e = 1 2πε0 p z3 (electric dipole). let eact be the actual magnitude. by how much is the ratio eappr/eact less than 1?

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2
