A charge 2Q is located at the origin while a second charge –Q is located at x = a. Where should a third charge be placed so that the net force on the charge is zero?

If the third charge is placed at a distance the net force on the charge will be zero

Explanation:

Consider the diagram below.

Let us add a new charge Q at a distance b from the origin.

Let the force that the charge 2Q exert on the new charge (Q) be

Let the force that charge -Q exerts on the new charge be

For the third charge in equilibrium,

Solving this will give us a quadratic equation which will be further simplified.

Making b the subject of the formula, we can get the distance that the third charge will be placed .

So if the third charge is placed at a distance the net force on the charge will be zero

if real values were plugged in, it will be easier for us to determine the value of b

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.
