Question

which of the following is false? two objects, both having positive charge, repel each other. two objects having unlike charges attract each other. electrostatic forces are responsible for the energy absorbed or released in chemical changes. the region in space where magnetic or electrostatic forces are effective is called a force field. all of the above are true.

Explanation:

1. Like - charged objects repel each other, so two objects with positive charge repel, which is true.
2. Unlike - charged objects attract each other, which is true.
3. Electrostatic forces are not responsible for energy in chemical changes. Chemical energy is related to the breaking and forming of chemical bonds, not electrostatic forces in the context of chemical reactions.
4. A force field is a region in space where magnetic or electrostatic forces are effective, which is true.

Answer:

Electrostatic forces are responsible for the energy absorbed or released in chemical changes.
