← A dust grain of mass 0.32 mg carries a charge of 4.0 nC. It is let go from rest on a smooth horizontal glass plate, in a horizontal uniform electric field of 4.0 × 10³ N/C. How fast is it moving after it has moved 0.07 m?A dipole of moment 3.0 × 10⁻⁹ C m is let go from rest at 60° to a uniform field of 1.5 × 10⁵ N/C. What is its kinetic energy when it has turned to 25° from the field? →
