2. If an object is positively charged, theoretically the mass of the object ______ a) Increases slightly by a factor of 9.11*10-31 kg b) Decreases slightly by a factor of 9.11*10-31 kg c) Remains the same d) May increase or decrease
Answer: b Explanation: If an object is positively charged it loses some of its electrons. The mass of an electron is 9.11*10-31 kg. So, if a positively charged body loses ‘n’ number of electrons, it mass decrease by the amount n*9.11E-31kg.
