Acts along the line joining the two point charges. Is proportional to the product of the two charges (q1. q2) Is proportional to the inverse of the square of the distance between the two charges.
Q. What direction is the net force on q1?
Use Coulomb’s law (equation 19-5) and the superposition of forces to find the net electrostatic force (magnitude and direction) on q2. The force from q1 will be attractive and to the left, and the force from q3 will be attractive and to the right.

Q. What is q1 and q2 in Coulomb law?
where Q1 represents the quantity of charge on object 1 (in Coulombs), Q2 represents the quantity of charge on object 2 (in Coulombs), and d represents the distance of separation between the two objects (in meters). The symbol k is a proportionality constant known as the Coulomb’s law constant.
Q. How do you solve r in Coulomb’s law?
r is the shortest distance between the charges (in m), ke is the Coulomb’s constant. It is equal to 8.98755 × 10⁹ N·m²/C² .
Q. What happens if Coulomb’s force disappears?
Disappearance of coulomb force removes the energy barrier that holds nuclei of the atoms apart. The same is conceivable to happen to Earth and all light elements start to fuse and eventually make iron nuclei. There will be a dramatic volumetric collapse and release of energy.
Q. Is electrostatic force a non contact force?
Electrostatic forces are non-contact forces; they pull or push on objects without touching them. Charged objects pull on other uncharged objects and may either push or pull on other charged objects.
Q. What is the range of Coulomb force?
Like charges repel, unlike charges attract. Coulomb’s law describes a force of infinite range which obeys the inverse square law, and is of the same form as the gravity force. and r = meters, F= x 10^ Newtons. A negative force implies an attractive force.
Q. Why do electrical forces dominate between atoms that are close together?
Electrical forces are the dominant forces for atomic-sized objects, since the gravitational forces between tiny objects like protons and electrons are negligible – it takes a BIG object to exert an appreciable gravitational force! These electrons are free to move throughout the metal.
Q. What quantities do electrical forces depend on?
The attraction or repulsion between charged particles is called electric force. The strength of electric force depends on the amount of electric charge on the particles and the distance between them. Larger charges or shorter distances result in greater force.
