eason for each effect. i) A capacitor creates an electric field which is then observed in another frame of reference. The field is perpendicular to the direction of motion. ii) A capacitor creates an electric field which is then observed in another frame of reference. The field is parallel to the direction of motion. iii) A long wire creates a magnetic field which is then observed in another frame of reference moving along the wire. Comment on what types of forces would be experienced by a charged particle (e.g. an electron) that is stationary in the frames of the capacitor and wire. Discuss why fields parallel to the direction of motion do not show any effect. Include appropriate diagrams and/or sketches.
