Imagine that you are sitting in a chamber with your back to one wall. An electron beam, moving horizontally from the front wall towards the back wall, is deflected by a strong magnetic field to your right side. What is the direction of the magnetic field? Name the rule used to find out the direction of magnetic field in this situation

Flemmings' left hand rule  and Downward direction

Explanation:

The person could able to determine the path of force by applying the left-hand rule of Fleming.

Via holding the thumb the forefinger and second finger at right angles for one other

The left-hand rule is applied in the electric motors

On the other hand, the right-hand rule is applied for electric generators.

So different hands are used for the different thing as there is a difference between the cause and effect

Therefore in this case there is a left hand rule used and the direction is downward

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 .
