Homework Statement
two similar charged bodies are kept 5 cm apart in air. If the second body is shifted away from the first another 5 cm, there force of repulsion will be?
Homework Equations
Coulomb's law? F= k (q1q2)/r^2?
Deebu R said:force of attraction or repulsion is directly proportional to product of charges and inversely proportional to square of the distance between them. So...if the r is moved by another 5 cm r^2 also increases.
When r= 5 r^2 = 25
When r=10 then r^2 is 100
Since it is inversely proportional the force reduces by 1/4. True?
Coulomb's Law is a physical law that describes the force of repulsion between two charged objects. It states that the force of repulsion is directly proportional to the product of the two charges and inversely proportional to the square of the distance between them. This means that the greater the charges and the smaller the distance between them, the stronger the repulsive force will be.
To calculate the force of repulsion between two charged bodies, you can use the equation F = k * (q1 * q2)/d^2, where F is the force of repulsion, k is the Coulomb's constant (9x10^9 N*m^2/C^2), q1 and q2 are the charges of the two bodies, and d is the distance between them.
Yes, Coulomb's Law can be used for both like and unlike charges. The only difference is that for like charges (both positive or both negative), the force of repulsion will be positive, while for unlike charges (one positive and one negative), the force of repulsion will be negative, indicating an attractive force.
The distance between two charged bodies has an inverse relationship with the force of repulsion. This means that as the distance between the two bodies increases, the force of repulsion decreases. This is because the farther apart the charges are, the weaker the electric field between them, resulting in a weaker force of repulsion.
Coulomb's Law and the force of repulsion between charged bodies are used in many real-life applications, including electronic devices, such as computers and smartphones, which rely on the repulsion between charged particles to function. Additionally, it is used in the design of power lines, circuit breakers, and other electrical equipment. It is also important in understanding the behavior of atoms and molecules, as the interactions between charged particles play a crucial role in chemical reactions.
