Power generation and its energy storage Electrical circuits and battery inventions Electric charge and electric fluid concepts Electrons and protons in atomic studies 2 / 10 What did the ancient Greeks discover about amber when rubbed with wool? Amber attracted nearby objects. Amber stopped attracting things. Amber became significantly heavier. Amber repelled nearby objects. 3 / 10 Which statement given below is NOT correct: Negative charge is possessed by electrons Positive charge is possessed by protons Neutron has equal number of positive and negative charges A neutral atom has equal number of positive and negative charges 4 / 10 Who is often credited with documenting the amber effect in ancient Greece? Pythagoras, a scholar known for math and harmonics Thales of Miletus, a Greek mathematician and philosopher Aristotle, an ancient philosopher and polymath Plato, a philosopher famous for his written works 5 / 10 What happens during charging by friction? Both objects lose some neutrons during the rubbing process. Neutrons exchange happens, leaving objects positively charged. Protons transfer equally between objects that are neutral. Electrons move between neutral objects when rubbed together. 6 / 10 What is the title of William Gilbert’s book published in 1600? On the Magnet The Principles of Magnetism Electroscope and its Effects The Amber Effect 7 / 10 What happens to the net electric charge in a closed region over time? It decreases consistently by processes It grows steadily over time instead It varies randomly without any pattern Net electric charge remains unchanged 8 / 10 What type of atom is formed when one or more electrons are gained by it? It stays neutral with no change at all It might become an atomic isotope of an element It forms a positive ion It forms a negative ion, 9 / 10 What happens when two glass rods rubbed with silk are brought close to each other? They repel each other They attract each other They stick together They do nothing despite being rubbed 10 / 10 What are quarks' charges compared to that of an electron? The quark charge is simply opposite to the electron. Quarks have charges as fractions of an electron's. Quarks hold charges equal to one electron's charge. Every quark has charges higher than an electron's. Your score is 0% Restart quiz
