Answer:
1. Attraction is used as a test for identifying an electrically charged object. False
2. Distance & displacement are different concepts. True
3. The interaction that brings about the acceleration is called force. True
4. Electrically charged objects attract charged objects. False
Explanation:
- Coulomb electrostatic force is used as a test for identifying an electrically charged object.
- Distance is a scalar quantity that refers to "the amount of ground covered by an object while moving". Displacement is a vector quantity related to "how far an object is displaced". This is the global change in the object's position.
- As the force applied to an object increases, the acceleration increases proportionately. Since the mass does not change even if the acceleration increases, it can be said that force = acceleration. That is, doubling the force also doubles the acceleration.
- They attract only neutral objects.A charged object, whether positively or negatively charged, has an attractive interaction with a neutral object. Positively charged and neutral objects attract each other. Negatively charged and neutral objects attract each other.
