Krypton – Mass Number – Neutron Number – Kr 2020-11-21 by Nick Connor Krypton is a chemical element with atomic number 36 which means there are 36 protons and 36 electrons in the atomic structure. The chemical symbol for Krypton is Kr.
Assuming no other forces acting on the particle, it must obey Newton's 2nd Law, as follows:
There are two forces acting on the particle in the vertical direction, one due to the electric field, and the other due to gravity.
Since the particle is positively charged, assuming that the electric field aims upward, we can write the following expression for the left side of (1):
Since we know that q/m = 0.1 C/kg,
⇒ q = 0.1m C/kg
Replacing this value of q in (2), and simplifying masses, we get:
We can find the value of a, simply applying the definition of acceleration:
