Quadratic Polynomial is of the Form $ax^2 + bx+c$. Geometrically it is represented by the Parabola on the Graph. The zeroes or the root of the quadratic are the point on x-axis where it intersect the x-axis. Here in this post of Quadratic graphs worksheet , we have asked upon few questions based on these

Prime Numbers
A prime number can be divided, without a remainder, only by itself and by 1. For example, 19 can be divided only by 19 and by 1.
Interesting facts about prime
•The only even prime number is 2. All other even numbers can be divided by 2.
•If the sum of a number’s digits is a multiple of 3, that number can be divided by 3.
•No prime number greater than 5 ends in a 5. Any number greater than 5 that ends in a 5 can be divided by 5.
•Zero and 1 are not considered prime numbers.
•Except for 0 and 1, a number is either a prime number or a composite number. A composite number is defined as any number, greater than 1, that is not prime.

This post is all about how you can easily solve electric force and electric field problems. At a glance problems of physics can seem to be scary and overwhelming for some students but do not worry all you need to do is your willingness to solve problem. So first of all you need to read your problem carefully and then start using following protocol to solve your problems. The procedure I am going to write is for calculating electric forces but you can use the same procedure to calculate an electric field by simply replacing the charge of interest, q, with a convenient test charge and dividing by the test charge at the end. So, to calculate the force,
