2: Use the following information to answer the next question.
A plastic straw is rubbed against a polythene bag and brought near an arrangement of a metal strip and gold leaves (as shown in the given figure). The different body are labelled as i, ii, ii and iv respectively. All these bodies wil become charged.
The charges on bodies i, ii, iii and iv will be respectively.
A. Positive, positive negative and negative.
B. Negative, negative, positive and positive.
C, Negative, positive negative, and positive.
D. Positive, negative, positive, and negative.
Dear student,
The answer to the question is C.As convention, the charge carried by the plastic straw rubbed against a polythene bag will create a negative charge on the plastic straw. According to the electrostatic induction in gold leaf experiment, the charge on the plastic straw and gold leaf will be negative as seen in the repulsion of the gold leaves and the charges on the metal strip will be positive.
Hope this will clear your doubts about the topic.
