## Homework Statement

A rod 11.9 cm long is uniformly charged and

has a total charge of −17.7 μC.

Find the magnitude of the electric field

along the axis of the rod at a point 46.2418 cm

from the center of the rod. The Coulomb con-

stant is 8.98755 × 109 N · m2/C2.

lecture problem I am trying to review for an exam in 3 hours.

our prof got this formula, but it isn't working for the numbers?

E = KQ / (a(a + l))

where K is columbs constant,

l = .119m

a = .462418m

Q = .0000177
