A copper sphere of mass `2g` contains nearly `2xx10^(22)` atoms. The charge on the nucleus of each atom is `29 e`. What fraction of the electrons must be removed from the sphere to give it a charge fo `+ 2muC` ?

Text Solution

AI Generated Solution

To solve the problem step by step, we will follow the logical sequence of calculations based on the information provided in the question. ### Step 1: Calculate the total number of electrons in the copper sphere. Given: - Mass of the copper sphere = 2 g - Number of atoms in the sphere = \( 2 \times 10^{22} \) - Charge on the nucleus of each atom = \( 29e \) ...
