Question
An object has a charge of $-2.0 \mu \mathrm{C}$ . How many electrons must be removed so that the charge becomes $+3.0 \mu \mathrm{C} ?$
Step 1
0 \mu \mathrm{C}$ to $+3.0 \mu \mathrm{C}$. This can be done by subtracting the final charge from the initial charge. In this case, the change in charge is $+3.0 \mu \mathrm{C} - (-2.0 \mu \mathrm{C}) = +5.0 \mu \mathrm{C}$. Show more…
