To point charges q1= uC, and q2= -4.8 are separated by a distance d= 8.0
On each of the spheres is there an excess or a deficiency of electrons? How many electrons?
To determine whether there is an excess or deficiency of electrons on each of the spheres, we first need to understand the concept of charge and how it relates to the number of electrons.
Charge can exist in two forms: positive (+) and negative (-), represented by the symbols q and -q, respectively. Electrons carry negative charge, so if an object has an excess of electrons, it will have an overall negative charge. Conversely, if it has a deficiency of electrons, it will have an overall positive charge.
In this case, we have two point charges: q1 = +u C and q2 = -4.8 C. Since q1 has a positive charge, it implies a deficiency of electrons. Similarly, since q2 has a negative charge, it implies an excess of electrons.
To determine the number of excess or deficient electrons, we need to know the elementary charge, represented by the symbol e, which is the charge carried by a single electron. The elementary charge is approximately 1.6 x 10^-19 C.
Using the elementary charge, we can calculate the number of electrons:
Number of electrons = (Charge of the object) / (Elementary charge)
For q1:
Number of electrons on q1 = (q1) / (e) = (+u C) / (1.6 x 10^-19 C)
For q2:
Number of electrons on q2 = (q2) / (e) = (-4.8 C) / (1.6 x 10^-19 C)
By substituting the given values, we can calculate the number of electrons on each sphere.
