Grade 12Electrostatics
A thin uniform rod extends along z-axis from z= -d to z=d. The rod carries a positive charge Q uniformly distributed along its length 2d with charge density t=Q/2d.
a) claculate the electric potential at a point z>d along z axis.b)What is the change in potential energy if an electron moves from z=4d to z=3d.
c)if the electron started out at rest at the point z=4d what is its velocity at z=3d.?
