Well I wouldn't quite call it a third eye but yes we have the ability to see things if we connect to our inner selves

Not physically, but I will see our third eye let us imagine in our mind. We are able to imagine things that we haven't seen. Thats because of our imagination skill. I will call this, third eye.

The final charge on each of the three separated spheres in part (b) is +3.0 μC. How many electrons would have to be added to one

marishachu [46]

Answer:

$1.873\times 10^{13}$ electrons should be added to one of these spheres to make it electrically neutral.

Explanation:

Total charge on each sphere = +3.0 μC = $3\times 10^{-6} C$

$1 \mu C=10^{-6} C$

In order to neutralize the positive charge equal magnitude of negative charge is to be added.

Total charge electrons, Q= -3.0 μC = $-3\times 10^{-6} C$

Number of electrons = n

Charge on a single electron, e = $-1.602\times 10^{-19} C$

Q = n × e

$-3\times 10^{-6} C=n\times (-1.602\times 10^{-19} C)$

$n=\frac{-3\times 10^{-6} C}{-1.602\times 10^{-19} C}=1.873\times 10^{13}$

$1.873\times 10^{13}$ electrons should be added to one of these spheres to make it electrically neutral.

Va=30mls

Vb=90mls

Ma=0.6M

Mb=?

from

Mb=Ma×Va×nb

 Vb×na

Mb=0.6×30×1
