Two identical metallic spheres, labelled A and B, carry excess charges of +1uC (sphere A) and +3UC(sphere B)
What is the charge on sphere B in e, the elementary charge unit? Assume that they have not touched and that the charge has not redistributed.
The elementary charge unit, e, is the charge of a proton or an electron, which is approximately 1.6 x 10^-19 Coulombs.
First, we need to find the charge on sphere B in Coulombs. Since the charge on sphere B is +3 UC, the charge in Coulombs can be calculated as:
Charge on B in Coulombs = (3 UC) x (1 x 10^-6 C/1 UC) = 3 x 10^-6 C
Now, we can convert this value to the elementary charge unit (e). The charge on B in e can be calculated as:
Charge on B in e = (3 x 10^-6 C) / (1.6 x 10^-19 C/e) = 1.875 x 10^13e
Therefore, the charge on sphere B in the elementary charge unit (e) is approximately 1.875 x 10^13e.
