Four identical metallic objects carry the following charges:

$+1\mathrm{.}33,+6\mathrm{.}75,-4\mathrm{.}88,$ and $-9\mathrm{.}98$C$.$ The objects are brought

simultaneously into contact, so that each touches the others. Then

they are separated. $($a$)$ What is the final charge on each object?

$($b$)$ How many electrons $($or protons$)$ make up the final charge on

each object? $($a$)$ Number Units
