What is Coulomb\'s law |
|
Answer» A law stating that charges repel and opposite charges attract,with a force proportional to the product of the charges and inversely proportional to the square of the distance between them . And it is the S.I. unit of charge. s inverse-square law, is a law of physics that describes force interacting between static electrically charged particles. In its scalar form, the law is:{\\displaystyle F=k_{e}{\\frac {q_{1}q_{2}}{r^{2}}}} {\\displaystyle F=k_{e}{\\frac {q_{1}q_{2}}{r^{2}}}},where ke is Coulomb\'s constant (ke = 8.99×109 N m2 C−2), q1 and q2 are the signed magnitudes of the charges, and the scalar r is the distance between the charges. The force of interaction between the charges is attractive if the charges have opposite signs (i.e., F is negative) and repulsive if like-signed (i.e., F is positive). |
