A sphere of radius 40 : cm has a total charge of +26 : & C uniformly distributed throughout its volume. Calculate the electric-¡eld magnitude at distances of ( a ) 0 cm ; ( b ) 10 : cm ; ( c ) 40 : cm ; ( d ) 60 : cm with respect to the sphere¢s center. 2. Serway & Jewett Problem 24 : 20 . The linear charge density of a long, straight ¡lament is & 90 : & C =m . Find the electric ¡eld at perpendicular distances of ( a ) 10 : cm ; ( b ) 20 : cm ; ( c ) 100 cm with respect to the ¡lament¢s axis. 3. Serway & Jewett Problem 24 : 23 . A 10 :- g piece of Styrofoam carries a net charge of & : 700 & C and £oats above the center of a large, horizontal sheet of plastic that has a uniform surface charge density ¡ . Determine the value of ¡ . 4. Serway & Jewett Problem 24 : 33 . A long, straight metal rod has a radius of 5 : 00 cm and a linear charge density of...
