How many e must be removed?
Answer: removing each electron will give u 1.603*10^-19 C positive charge. So if u want +1*10^-7 C u need to remove +1*10^-7 / 1.603*10^-19 = 6.2383*10^11 electrons.
What is the amount of charge possessed by 1 kg?
Answer. Electrons in 1kg: 1/(9.11 * 10^-31) = 1.10 * 10^30.
What is charge of 25 kg of electron?
Answer: The charge qe on a single electron is −1.6×10−19C.
What is the amount of charge?
The amount of charge is given the symbol Q and is measured in units of coulombs (C). The quantity of charge (or electricity) contained in a current running for a specified time can be calculated: Q = I × t. Q = quantity of charge (electricity) in coulombs (C) I = current in amperes (amps, A) t = time (seconds)
How much positive and negative charge is there in 250g of water?
250 ml = 250 gram of water since its density is 1 in cgs. One molecule of water has 2 hydrogen atoms (2 protons) and one oxygen atom (8 protons). So 250 g water will have 10 x 8.36 x 1024 = 8.36 x 1025 protons. So one cup of water has 13.3 mega coulomb positive and negative charge, so that the overall charge is zero…
How much positive and negative charge is there in water?
Totally they will be neutral. Was this answer helpful?
What is the positive and negative charge of water?
The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms. When a neutral molecule has a positive area at one end and a negative area at the other, it is a polar molecule.
How much positive and negative charge is there in a cup of water Doubtnut?
Therefore the number of molecules in one cup of water is (250/18)×6.02×1023. Each molecule of water contains two hydrogen atoms and one oxygen atom, i.e., 10 electrons and 10 protons. Hence the total positive and total negative charge has the same magnitude. It is equal to (250/18)×6.02×1023×10×1.6×1019C=1.34×107C.
How much negative charge is there in a cup of water?
Each molecule of water contains 2+8=10 electrons and protons. Was this answer helpful?…Thank you.

What is the total charge on 75kg of electrons?
The total charge q on n number of electrons is the product of the number of electrons and the charge on a single electron. Substitute 8.33×1031 for n and 1.6×10−19C for qe in the above equation. Therefore, the total charge on 75 kg of electrons is −1.33×1013C. So, the correct answer is “Option C”.
Is a charge of 5.8 into 10 to the power minus 18 Coulomb possible?
Remember to accommodate the level of precision of the value in the posted question. How many elementary charges does this correspond to? 5.8 × 10⁻¹⁸ C / (1.602 2 × 10⁻¹⁹ C/e) = 36.20e. Therefore, yes, there could be such a charge, which corresponds to 36 protons.
What is the total charge on a 45 kg of electrons?
