A charged nonconducting rod, with a length of 2.00 m and a cross-sectional area of 4.00 cm2, lies along the positive side of an x axis with one end at the origin. The volume charge density r is charge per unit volume in coulombs per cubic meter. How many excess electrons are on the rod if r is (a) uniform, with a value of -4.00 mC/m3, and (b) nonuniform, with a value given by r = bx2, where b=-2.00 mC/m5?

Question
A charged nonconducting rod, with a length of 2.00 m and a
cross-sectional area of 4.00 cm2, lies along the positive side of an x
axis with one end at the origin. The volume charge density r is
charge per unit volume in coulombs per cubic meter. How many
excess electrons are on the rod if r is (a) uniform, with a value of
-4.00 mC/m3, and (b) nonuniform, with a value given by r = bx2,
where b=-2.00 mC/m5?
