Answer:
The magnetic field required required for the beam not to be deflected is
Explanation:
From the question we are told that
The charge on the particle is
The mass of the particle is
The potential difference is
The potential difference between the two parallel plate is
The separation between the plate is
The Kinetic energy experienced by the beam before entering the region of the parallel plate is equivalent to the potential energy of the beam after the region having a potential difference of 1.8kV
Generelly
And
Equating this two formulas
making v the subject
Substituting value
Generally the electric field between the plates is mathematically represented as
Substituting value
the magnetic field is mathematically evaluate
Answer:
10,000 eV
Explanation:
Due to the law of conservation of energy, the kinetic energy of the electron at the end of its path is equal to its initial electric potential energy, given by:
where
q is the electron charge
is the potential difference
Here we have:
is the electron's charged
is the potential difference
Substituting into the formula, we have
Answer:
D. 214 kPa
Explanation:
The absolute pressure is given by:
where
p is the absolute pressure
is the atmospheric pressure
is the gauge pressure
In this problem, we have
So, the atmospheric pressure is
