Explanation:
#Apply surface charge density, electric field, and Gauss law to solve:
a. Surface charge density is defined as charge per area denoted as
, and the strength of the electric field outside the sphere
Using Gauss Law, total electric flux out of a closed surface is equal to the total charge enclosed divided by the permittivity.
#surface charge outside sphere.
Hence, the new charge density on the outside of the sphere is
b. The strength of the electric field just outside the sphere is calculated as:
From a above, we know the new surface charge to be ,
Hence, the strength of the electric field just outside the sphere is
Explanation:
According to Rydberg's formula, the wavelength of the balmer series is given by:
R is Rydberg constant for an especific hydrogen-like atom, we may calculate R for hydrogen and deuterium atoms from:
Here, is the "general" Rydberg constant,
is electron's mass and M is the mass of the atom nucleus
For hydrogen, we have, :
Now, we calculate the wavelength for hydrogen:
For deuterium, we have :
