When at rest a proton experiences a net electromagnetic force of magnitude 8.0 x 10-13 N pointing in the positive x direction. When the proton moves with a speed of 1.5 x 106 m/s in the positive y direction, the net electromagnetic force on it decreases in magnitude to 7.5 x 10-13 N, is it still pointing in the positive x direction?

the answer is 3.1 his answer is wrong mines is right

your answer is, orbit around the nucleus

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 .
