Electric force attracts tiny bits of paper. Explain by an activity and write your observations.
Answers
Answer:
here u go
Explanation:
When the negatively charged ruler is brought near to the paper pieces, they are attracted to the ruler as the the electrons move around on the paper because of the large charge on the ruler. Electrons will move away from the ruler leaving a positive charge on the paper near the ruler, so they are attracted
Activity: To show tiny bits of paper gets attracted to electric force.
Theory: Electrostatic force is the force exerted by one stationary object having electric charge on other stationary object having electric charge. If the charge on both the objects is same, they will repel and if the charge on both the objects is different then they will attract each other. There are mainly two types of charges: positive and negative.
Materials required: tiny bits of paper, plastic ruler/comb
Experiment:
•Rub the plastic ruler/comb with a sheet of paper.
•This process will ensure that the ruler/comb gets charged.
•Now immediately bring the ruler/comb towards the bits of paper.
Conclusion: We will observe that the bits of paper will be attracted towards the ruler/comb. This happens because the charge acquired by the ruler/comb exerts a force on the paper and thus attracts it.
