11 A plane surface is rotated in a uniform electric field. When
is the flux of the electric field through the surface
maximum?
a ) when the surface is perpendicular to the field

b) when the surface is parallel to the field

c) when the surface is at an angle of 30 degree with the field

d) when the surface is at an angle of 40 degree with the field

representative si the final answer! : )

it becomes positively charged by charging it

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 .

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
