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.

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

When a plastic rod is rubbed with a wool cloth, the wool acquires a positive charge. What is the best explanation for this effect?A protons are transferred to the clothB protons are transferred to the rodC electrons are transferred to the clothD electrons are transferred to the rod

A student pulls a plastic comb through her hair on a dry day.  Afterward, her hair is attracted to the comb.  Which of the following occurs when the comb passes through the hair?A.Total charge is conserved, and no charges are transferred between the hair and the comb.B.The comb gains electrons and the hair becomes positively charged.C.The comb gains electrons and the hair becomes negatively charged.D.Both the comb and hair become positively charged.

A plastic rod is rubbed with a piece of animal fur. The plastic rod acquires a negative charge during this process. Which of the following is true about the charge on the piece of fur?

A silk cloth gains electrons when rubbed over a glass rod. A different glass rod gains electrons when rubbed with rabbit fur. What will happen if the two charged glass rods approach one another and why? A. The rods will repel each other because they have unlike charges. B. There will be no reaction between the rods. C. The rods will attract each other because they are both positively charged. D. The rods will attract each other because they have unlike charges. E. The rods will repel each other because they have like charges.
