A charge +3q is placed at x = 0 and a charge +11q is placed at x = 5 units. Where, along the x-axis is the net force on a charge

RideAnS [48]

At x = 1.72 units the net force on a charge Q equal to zero when a charge +3q is placed at x = 0 and a charge +11q is placed at x = 5 units.

A net force is defined as the sum of all the forces acting on an object. The equation below is the sum of N forces acting on an object. There may be several forces acting on an object, and when you add up all of those forces, the result is what we call the net force acting on the object.

This equation is the sum of n forces acting on an object. The magnitude of the net force acting on an object is equal to the mass of the object multiplied by the acceleration of the object, as shown in this formula.

+3q ⇔ +11q

x = ? ⇔ x = 5

$\frac{1}{4\pi E0} (\frac{3q}{x^{2} } -\frac{11q}{(5-x)^{2} } ) = 0$

$\frac{3}{x^{2} } = \frac{11q}{(5-x)^{2} }$

$\frac{5-x}{x} = \sqrt{\frac{11}{3} } = 1.91\\$

$5-x = 1.91x\\x = 1.715 = 1.72 units$

∴ At x = 1.72 units the net force on a charge Q equal to zero

It shows gas particles leaving the car exhaust what procees

Lubov Fominskaja [6]

The gas particles leaving the car exhaust show the process of combustion.

<h3>What is the process of combustion?</h3>

Combustion refers to a chemical process in which a substance reacts with oxygen to give off heat. The original substance is known as the fuel, whereas the source of oxygen is known as the oxidizer. The fuel can be present in solid, liquid, or gas, but for an airplane, the fuel is usually a liquid form. Combustion also called burning that is the basic chemical process of releasing energy from a fuel and air mixture. In an internal combustion engine, the ignition and combustion of the fuel occurs within the engine. The engine converts the energy from the combustion process to work.

So we can conclude that the car releases gases due to the process of combustion.
