Question

difference between square root and the root of quadratic equation​

Answer 1

Step-by-step explanation:

a)

Electric force on a charged particle of charge placed in electric field of magnitude is given by,

However, this electric force balances the weight of the electron. So,

Here, is mass of the electron andis acceleration due to gravity.

Solve for

Substitute for,forandfor

As the weight of the object directed downwards, the direction of electric force must be upwards. As the direction of electric force on negatively charged particle is opposite to the direction of electric field, the direction electric filed is downward.

Hence, the magnitude of electric field isand direction is downwards.

Answer 2

Answer:

Square Root-

In mathematics, a square root of a number x is a number y such that y2 = x; in other words, a number y whose square (the result of multiplying the number by itself, or y ⋅ y) is x.

For example, 4 and −4 are square roots of 16 because 42 = (−4)2 = 16

The Root of Quadratic Equation -

Every quadratic equation gives two values of the unknown variable and these values are called roots of the equation.

Let ax² + bx + c = 0 be a quadratic equation. If aα² + bα + c = 0 then α is called a root of the quadratic equation ax² + bx + c = 0.
