Rubbing the PVC pipe gave it a negative charge. Based on your observations in Part 1, determine what charge was on the surface of the polystyrene balls. NegativeNeutralPositive

Rubbing the PVC pipe with the cloth gave the rod a negative charge.Determine which charge you would expect the cloth to gain. NegativeNeutralPositive

A polythene ruler and a cotton cloth are electrically neutral.  When the ruler is rubbed with the cloth, the ruler becomes negatively charged.  Why does this happen?Protons (positive charges) are transferred from the ruler to the clothElectrons (negative charges) are transferred from the ruler to the clothProtons (positive charges) are transferred from the cloth to the rulerElectrons (negative charges) are transferred from the cloth to the ruler2Which of the following is NOT due to static electricity?A lightning strikeA bulb lighting up when connected to an electric circuitA balloon being attracted to a wallA ruler being used to pick up pieces of paper3When a positively charged rubber balloon is placed in contact with a neutral wall, it appears to ‘stick’ to the wall.  Which of the following best explains why this happens?Electrons (negative charges) in the wall are attracted towards the balloonProtons (positive charges) in the wall are repelled away from the balloonProtons (positive charges) in the wall are attracted towards the balloonElectrons (negative charges) in the wall are repelled away from the balloon4Which of the following CANNOT be easily be charged by friction?A piece of paperA sheet of aluminium foilThe rubber sole of a shoeSome plastic cling film5Which of the following atoms is NOT electrically neutral?One which contains 2 protons, 2 neutrons and 1 electronOne which contains 2 protons, 2 neutrons and 2 electronsOne which contains 1 proton and 1 electronOne which contains 3 protons, 4 neutrons and 3 electrons

polythene rod was rubbed with a cloth. Afterwards the rod was found to be negatively charged. Has the cloth gained or lost electrons?lost electronsgained electrons

A neutrally charged plastic pen was rubbed against a silk cloth making the plastic pen a negatively charged object after the charging process. Why does the plastic pen becomes negatively charged?Group of answer choicesElectrons from the plastic pen were transferred towards the silk cloth.Neutrons from the silk cloth were transferred towards the plastic pen.Electrons from the silk cloth were transferred towards the plastic pen.Protons from the silk cloth were transferred towards the plastic pen.

In the classroom activity, you were able to make the plastic float above the balloon because........ aThe charge on the plastic was negative and the charge on the balloon was positive. bThe charge on the plastic was positive and the charge on the balloon was negative. cThe charge on the plastic and balloon were both negative. dThe charge on the plastic and balloon were both positive.
