Question

What is the formula for electrostatic force?

Answer 1

F = k $\frac{q1 q2 }{ r^{2} }$

k - coefficient
q1 and q2 - charge
r - distance btw them

Answer 2

$\huge\rm Electrostatic \:force$

This is a type of force, which causes attraction or repulsion between two particles due to Electric Charges.

Like charges repel and unlike charges attract.

Example :- Rubbing a scale on oily hair, attracts pieces of paper, here both of them accumulate Unlike Charges, as paper has Negative charge while scale has Postive charge

Additional Information

• Electrostatic Force is a non contact Force, because it doesn't require contact with other body, they push or pull objects without getting touched

• Electrostatic Force is also called Coulomb Force or Coulomb interaction.

• It is named after a French Physicist Charles - Augustin de Coulomb.

• The electrostatic force acts in about, one-tenth of the diameter of atomic nucleus.

• Electrostatic Force is $\bf 10^{36}$times, greater than Gravitational Force.

• Electrostatic follows Inverse Square laws that is it is inversely proportional to the square of the distance from the source.

Coulomb's Law Formula:-

$\huge \bf F = k \dfrac{q_{1} q_{2} }{r^{2} }F=k$
