Total initial charge: (+3e)+(+5e)+(−3e)=5e When conductors touch, charge redistributes while conserving total charge. The total charge remains 5e, so the final charges must sum to 5e. Now, checking the options: Possible answers: (b) and (c). Class 12th Science Physics NCERT ...

Object X is negatively charged and is repelled by object Y, meaning Y must also be negatively charged. Object Z is attracted to object Y. Since Y is negative, Z could be positively charged (opposite charges attract) or neutral (neutral ...
The charge of one electron is − 1.6 × 10−¹⁹ C. The object gains 5.0 × 10¹⁸ electrons, resulting in a charge change of: q = (5.0 × 10¹⁸) × (−1.6×10⁻¹⁹) = −0.80C Net charge = 1C−0.80C= +0.20C. Correct answer: ...
The correct answer is:(c) Intercropping Intercropping is the practice of growing two or more crops simultaneously on the same field in a definite pattern (e.g., in alternate rows or strips). It helps in better resource utilization, pest control, and soil ...
The correct answer is:(d) (i) and (iii) Manure improves the water-holding capacity of sandy soil by increasing its organic matter. Manure is rich in organic matter but contains small amounts of nutrients compared to chemical fertilizers. Class 9th Science NCERT ...
