The mass of the bead is
The magnitude of the electric field is
The acceleration of the bead is
Generally, the electric force on the bead is mathematically represented as
Where q is the charge on the bead
Now the gravitational force opposing the upward movement of the bead is mathematically represented as
Generally the net force on the bead is mathematically represented as
=>
Now substituting values
