Question

14.2.2 Represent and reason Two positively charged objects are held near each other in the muzzle of a cannon (see part a of the illustration) When the "trigger" holding the cannonball is released, the positively charged cannonball flies out the end of the muzzle in part b. Certain types of energy have increased. Describe some type of energy decrease that you think might compensate for the increase in these other energies. Note: The situation shown in part a of the illustration is similar to that of a compressed spring; instead of the coils of the spring being squeezed together, two like charges are squeezed or pushed together. In part b of the illustration, this compressed electric "spring" is more relaxed. Fill in the table that follows. a. b. Draw an energy bar chart representing the initial and Using the language of energy, explain in words the described process, going from the initial state to thefinal states final state. Indicate your system choice.

Explanation / Answer

When the two positively charged objects are very close then they have electrostatic potential. As they got separated due to mutual interaction ( repulsive force) then potential start decreasing while kinetic energy will be increasing.

So the energy decreased is potential while the increased one is kinetic energy.
