What does the shading of the electric field arrows represent in terms of magnitude or strength of the electric field? How does this relate to the voltage reading on the equipotential meter

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

0.11 m/s and 0.28 m/s should be correct
