two forces of 1.5N and 2.0N act vertically at two ends of a meter scale. Where and in what direvtion should a force should be applied so that the scale remains horizontally stable

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                                         : )

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
