They are repelled by the glass rod’s strong electrification. They disappear after some time near the charged glass rod. They stop moving completely when placed next to the glass. They are attracted by the glass rod due to its charge. 2 / 10 What is surface tension mainly caused by? Electric forces Magnetic forces Nuclear forces Gravitational forces 3 / 10 What is the origin of the Neo-Latin word electrica coined by William Gilbert? The Latin word for thunder or lightning The Old English word related to fire energy The Greek origin word relating to energy fields The Greek term ēlektron meaning amber resin 4 / 10 In ancient records, what material besides amber was noted for a similar 'attracting power? Quartz crystal with no such property Polished marble used in sculptures Heraclean Stone, also called loadstone Dark obsidian with shiny surfaces 5 / 10 What term did Benjamin Franklin use to describe electricity instead of 'electric fluid'? Electric fire, describing flows and sparks. Power current driving electric systems. Electrical spark used for conduction effects. Electric essence within charged materials. 6 / 10 How is a glass rod charged when rubbed with silk? The glass rod stays neutral after being rubbed with silk. The glass rod loses its electrons and becomes positive. The glass rod gains its electrons and becomes negative. The silk cloth gives the rod protons to make it positive. 7 / 10 What happens when two plastic rods rubbed with cat’s fur are brought close? They lose their charge after a shorter duration They attract each other They repel each other They remain in contact without any repulsion 8 / 10 What happens between a glass rod and wool after being rubbed together? They repel each other They remain neutral They attract each other They lose their charge after being handled again 9 / 10 Which statement given below is true about the nature of all matter? Matter is always composed of molecules and atoms combined Matter consists of particles that carry electrical charge overall Matter is formed and shaped exclusively by gravitational forces Matter arises entirely from the application of magnetic effects 10 / 10 The electrified state of objects produced after rubbing because of the spontaneous imbalance of charges inside objects. transfer of charges between two objects. takes place as charges are destroyed in the rubbing interaction. happens because brand new charges are created during contact.
