Answer :
Final answer:
Coulomb's Law explains the force of interaction between charged particles, expressed in vector form. When charged spheres are immersed in a liquid, the force of attraction changes based on the permittivity of the medium.
Explanation:
Coulomb's Law is used to measure the force of interaction between charged particles in electrostatics.
Coulomb's Law in vector form is expressed as F = k(q1q2)/(r^2) r-hat, where F is the force vector, k is Coulomb's constant, q1 and q2 are the magnitudes of the charges, r is the distance between the charges, and r-hat is the unit vector in the direction from q1 to q2.
When two charged spheres immersed in a liquid of relative permittivity K attract with a force F, the spheres will attract with a force KF when the distance between the charges is kept constant.
