In a Cartesian coordinate system (x, y,z) between the two points P1= (1 cm, 2 cm, 1 cm) and P2= (4 cm, 2 cm, 6 cm) there is an electrical field which directs along the connection line from P1 to P2 at any point. The magnitude of the electrical field increases like 5Vcm3s2, where s is the distance from point P1. Calculate the electrical potential at a distance of 2 cm from Point P1 when the electrical Potential at a distance of 4 cm from Point P1 is zero​

does anyone know or what?

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .

there are no contact forces mentioned on the list of choices that you've provided.
