Teaching UP B.Ed (Paper 1 & 2) Mock Test 2025 Physics Electric Charges and Coulomb's Law Coulomb’s Law
According to Coloumb's law, the magnitude of the electrical force F between two charged particles separated by a distance r and having charges q1 and q2, is expressed as : (k is the electrostatic constant)
1
\(F=({k\over r^2}){q_1\over q_2}\)
2
\(F=k.{{q_1}.{q_2}\over r}\)
3
\(F=k.{{q_1}.{q_2}\over r^2}\)
4
\(F=k.{r^2\over {q_1}.{q_2}}\)
