Unformatted text preview: 180 Chapt. 23 The Electric Field a) a static electric field. b) a static magnetic field. c) a grass field. d) light. e) sound. 023 qmult 00220 1 1 1 easy memory: point charge electric field 6. The electric field about a point charge or any spherically symmetric charge distribution is given by vector E = kq r 2 ˆ r , where k = 8 . 987 ... × 10 9 Nm 2 / C 2 , r is the radius from the center of system, q is the charge inside of a shell of size r , and ˆ r is a/an: a) radially outward pointing unit vector. b) a radially inward pointing unit vector. c) an azimuthal angle unit vector. d) a polar angle unit vector. e) an r with tilde on it. 023 qmult 00230 1 4 4 easy deducto-memory: E-field for arbitrary charge distribution 7. “Let’s play Jeopardy ! For \$100, the answer is: The formula for a discrete set of charges is E ( vector r ) = summationdisplay i kq i | vector r − vector r i | 3 ( vector r − vector r i ) , where the sum is over all charges q i , vector r i is the charge location,...
