Three solid plastic cylinders all have radius 2.50 cm and length 6.00 cm.
(a) One carries charge with uniform density 19 nC/m2 everywhere on its surface. Find the charge of the cylinder.
(b) Another carries charge with the same uniform density on its curved lateral surface only. Find the charge of the cylinder.
(c) The third carries charge with uniform density 450 nC/m3 throughout the plastic. Find the charge of the cylinder.
