A thin rod extends along the z -axis from z = -d to z = d. The rod carries a positive charge Quniformly distributed along its length 2d with charge density 51.86 C/m. If the electron started out at rest at the point z = 4d, what is its velocity at z = 3d? (Take elementary charge 1,6x10 19 c, take Coulomb's constant 9x10° Nm?C2 and take mass of electron 9,1x10 31 kg). Write your answer in multiples of 1010 m/s. And write your answer in two decimal places. A thin rod extends along the z -axis from z = -d to z = d.
