Explanation:
From the question we are told that the
The magnitude of electric field is
The number of proton is
The distance between the plates is
The total charge can be mathematically represented as
Where e is the charge on one proton which has a value of
Substituting values
The change in potential energy is mathematically represented ads
where the negative sign shows that the work done by the electric force is against the electric field
Substituting values
The mass of the bead is given as 0.05kg
The change in potential due to gravity is mathematically given as
the negative sign is due to the fact that the height is decreasing
And
Making h the subject
