The potential (relative to infinity) at the midpoint of a square is 3.0 v when a point charge of +q is located at one of the corners of the square. what is the potential (relative to infinity) at the center when each of the other corners is also contains a point charge of +q?
a) 0 vb) 3.0 vc) 9.0 vd) 12 v

option d) 12.0 V

Explanation:

Data provided in the question:

Potential difference due to a single charge (+Q), E = 3.0 V

Now,

The Electric potential for the system of charges is given as:

given for single charge, E = 3.0 V =                 .......(1)

so thus, for 4 charges, we have

     ...............(2)

from 1 and 2 we have

E = 4 × 3.0 V = 12 V

Hence, option d) 12 V is the correct answer.

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 .

c) power lifting, will be your answer.
