Coulomb’s law formula<\/h3>\n\n\n\n

Coulomb’s law calculates the electric force F<\/em> in newtons (N) between two electric charges q<\/em>1<\/sub> and q<\/em>2<\/sub> in coulombs (C)<\/p>\n\n\n\n

with a distance of r<\/em> in meters (m):<\/p>\n\n\n\n

\"F=k\\frac{q_1\\cdot<\/figure>\n\n\n\n

F<\/em> is the force on q<\/em>1<\/sub> and q<\/em>2<\/sub> measured in newtons (N).<\/p>\n\n\n\n

k<\/em> is Coulomb’s constant k<\/em> = 8.988\u00d7109<\/sup> N\u22c5m2<\/sup>\/C2<\/sup><\/p>\n\n\n\n

q<\/em>1<\/sub> is the first charge in coulombs (C).<\/p>\n\n\n\n

q<\/em>2<\/sub> is the second charge in coulombs (C).<\/p>\n\n\n\n

r<\/em> is the distance between the 2 charges in meters (m).<\/p>\n\n\n\n

When charges q1 and q2 is increased, the force F is increased.<\/p>\n\n\n\n

When distance r is increased, the force F is decreased.<\/p>\n\n\n\n

<\/a>Coulomb’s law example<\/h3>\n\n\n\n
