To solve this problem we will start by calculating the electric field. This can be defined as the change in charge density over twice the permittivity constant in a vacuum. From this value we will proceed to calculate by the relations of energy and load, the relation with the speed and the position of the objective.
Our values,
The electric field due to very large insulating sheet can be calculated as
The relation between the electric field E and potential V is given by,
Therefore, the potential in terms of electric field can be written as,
The kinetic energy of the object is given by
The speed of the object then is
Replacing we have then,
Therefore the initial speed is 48.3322m/s
