Coulombâ€™s Law Questions

F is the electric force.
K is the coulomb constant. = 8.99 x10^9 NmÂ²/CÂ²
Q1 and Q1 are the charges
R is the distance between the charges

1. Q1 = +2 x (1.60 x 10^-19) = 3.2 x 10^-19 C
Q2 = +10 x (1.6 x 10^-19) = 1.6 x 10^-18 C
R = 3x10^-9 m => RÂ² = 9x10^-18) mÂ²

F = 5.11 x 10^-10 N

2. Q1 = 1 C
Q2 = 1 C
R = 1 km => 10Â³m. RÂ² = (10Â³)Â² = 10^6 m

F = 8.99 x 10Â³ N

3. Q1 = 1.6 x10^-19
Q2 = 1.6 x10^-19
R = 10^ -10 => RÂ² = 10^-20 m

F = 2.3 x 10^-8 ...
