Question
Open the “Electric Field Hockey” applet here: https://phet.colorado.edu/en/simulation/legacy/electric-hockey In this applet, you can drag positive and negative charges from the boxes at the upper right hand side of the screen into the “field”. These charges remain fixed in place. When you press “Start”, the black positively-charged “puck” will follow the electric fields established by the colored positive and negative charges that you placed in the field. The aim of the applet is to get the “puck” into the blue “goal” at the right side of your screen. Familiarize yourself with the controls and behavior of the puck. You can always remove charges from the field by dragging them back to the boxes at the upper right hand side of the screen.

21. It is a curvilinear motion. It occurs when a straight moving body is acted upon by a perpendicular force which changes its direction (centripetal force)
22. The motion is still curvilinear. At some point, the perpendicular force stops being perpendicular and starts to accelerate the charge. Hence, it is fastest near the negative charge and slowest when away from it.
