What force is responsible for the repulsion between two positively charged particles?

Electromagnetic force

Explanation:

When two stationary charges are placed at some distance from each other then the force of attraction or repulsion between then is given by the equation

here we know that

= two charges

r = distance between two charges

now we know that the two charges are repelling each other then they must be of same type and if two charges are attracting each other then it must be of opposite nature.

So here force between the two charges are electrostatic force

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 .
