54. (a) We consider the radial field produced at points within a uniform cylindrical distribution of charge. The volume enclosed by a Gaussian surface in this case is Lr π 2 . Thus, Gauss’ law leads to E q A Lr rL r == = || || () || . enc 0c y l i n d e ε ρ ε π π 2 00 22 c h (b) We note from the above expression that the magnitude of the radial field grows with r .

Unformatted text preview: (d) The largest value of r which encloses charged material is r max = R . Therefore, with | | . = 0 0011 C m 3 and R = 0.050 m, we obtain E R max | | . = = 2 31 10 6 N C. (e) According to condition 1 mentioned in the problem, the field is high enough to produce an electrical discharge (at r = R )....
