A thin rod extends along the z -axis from z = −d to z = d . The rod carries a positive charge Q uniformly distributed along its length 2d with charge density 91.9 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 9x109 Nm2C-2 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 long, thin rod (length = 3.0 m) lies along the x axis, with its midpoint at the origin. In a vacuum, a +9.0C point charge is fixed to one end of the rod, and a -9.0HC point charge is fixed to the other end. Everywhere in the x, y plane there is a constant external electric field (magnitude 4.0 x 103 N/C) that is perpendicular to the rod. With respect to the z axis, find the magnitude of the...

A thin, fixed rod is 30.0mm long and carries a total positive charge of 100.0nC distributed uniformly along its length. A single small positive point charge, Q=2.0 μC, is placed 180.0mm from the left end of the charged rod in a direction along the line of the rod. What is the total electrical force on the charge Q? Sign convention - if the force points left, enter it as negative, right as postive.
