Question

A glittering glass globe is given a net electric charge of 5.31 × 10^-6 C. Does the globe now have more or fewer electrons than it does in its neutral state? How many more or fewer?

Answer 1

If the glass globe has a net electric charge of 5.31 × 10^-6 C, it has 3.31 × 10^13 fewer electrons than it does in its neutral state.

Step-by-step explanation:

The number of electrons in an object can be determined by dividing the total charge by the charge per electron. In this case, if the glass globe has a net electric charge of 5.31 × 10-6 C, we can calculate the number of extra electrons or missing electrons.

Since electrons have a charge of -1.60 × 10-19 C, we can use the formula:

Number of electrons = Total charge / Charge per electron

Number of electrons = 5.31 × 10-6 C / -1.60 × 10-19 C

Number of electrons = -3.31 × 1013

Therefore, the globe now has 3.31 × 1013 fewer electrons than it does in its neutral state.
