An object that is 0.5 m above the ground has the same
amount of potential energy as a spring that is stretched 0.5
m. Each distance is then doubled.
How will the potential energies of the object and the spring
compare after the distances are doubled?
The gravitational potential energy of the object will be
two times greater than the elastic potential energy of the
spring
The elastic potential energy of the spring will be four
times greater than the gravitational potential energy of
the object
The elastic potential energy of the spring will be two
times greater than the gravitational potential energy of
the object
The potential energies will remain equal to one another

it was given as a lesson and guide for prayer.

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 .

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
