GENERAL INSTRUCTIONS

  1. Read all questions carefully before answering. - Misreading the question and then blaming the paper will not increase your marks.

  2. Show proper steps wherever required. - “Sir, answer toh yahi aana tha” is not an accepted mathematical method.

  3. Write neatly and clearly. - If your handwriting requires a decoder machine, checking may become an adventure.

  4. Manage your time wisely. - Spending 45 minutes on one question and calling the rest “optional” is not a strategy.

  5. If you do not know the answer, you may cry silently. - Loud crying, emotional speeches, and negotiations for hints are strictly prohibited.

VEDANT WORKSHEET SERIES Class XII – Physics Chapter 1: Electric Charges and Fields Time: 1 Hour Maximum Marks: 20 SECTION A – CASE STUDY BASED QUESTIONS (5 × 4 = 20 Marks) Case Study 1: Electrostatic Charges in Daily Life During winter, Riya notices that when she removes her woollen sweater, it crackles and sometimes small sparks are seen in the dark. This happens due to transfer of electrons between the sweater and her body because of friction. The body acquires electrostatic charge, which may later discharge through nearby conductors. Such phenomena demonstrate the conservation of electric charge and the behaviour of charges on insulating materials. Answer the following questions: a) What type of charging occurs when two objects are rubbed together? (1 Mark) b) State the law of conservation of charge . (1 Mark) c) If an object initially has zero charge and gains (3 \times 10^{12}) electrons during rubbing, calculate the net charge acquired by it. (Charge of electron = (1.6 \times ...
