Answer:
The radiation wavelength is 1.08 X 10⁻¹² m
Explanation:
Frequency is the ratio of speed of photon to its wavelength
F = c/λ
where;
c is the speed of the photon = 3 x 10⁸ m/s
λ is the wavelength of gamma ray = ?
F is the frequency of the gamma ray = 1/T
T is the period of radiation = 3.6x10⁻²¹ s
λ = T*C
λ = 3.6x10⁻²¹ * 3 x 10⁸
λ = 1.08 X 10⁻¹² m
Therefore, the radiation wavelength is 1.08 X 10⁻¹² m

Explanation:
According to the Coulomb's law, the magnitude of the electrostatic force of interaction between two charges and
which are separated by the distance
is given by
<em>where,</em> k is the Coulomb's constant.
For the case, when,
Then, using Coulomb's law,
For the case, when,
Then, using Coulomb's law, the new electric force between the charges is given by,
