A long solid copper cylinder has a radius of R=3.0cm and a uniform (linear) surface charge density of 4.5μC/m. What is the magnitude of the electric field, in newtons per coulomb, at a distance of 2.9 cm from the symmetry axis of the cylinder?

Daughter element the new element produced along with a decay particle in a nuclear transmutation 2. half-life the substance that decays in a nuclear transmutation 3. parent element the change of one chemical element into another by nuclear decay or radioactive bombardment 4. transmutation the time required for the decay of one-half of the atoms in a sample of radioactive material
