01 A body has positive charge. Does it mean it has no electrons?
Answer and explanation
Correct answer: A. No, it means deficiency of electrons, not absence
Explanation: The governing concept is net charge, which depends on the difference between positive and negative charges. A positively charged body normally still contains protons and electrons, but it has fewer electrons than the number needed for electrical neutrality. Thus option A is correct: positive charge indicates an electron deficiency, not total absence. Option B confuses net charge with composition, while C and D incorrectly change the nature or role of electrons and neutrons.
