Calculate the magnitude of the force acting on a charge 6Coulombs due to a charge of 19Coulombs at a distance of 15m away from it...?

Question

The force constant k is 9E9 [1/(Farad/m)]. Give your answer in GN where 1 GN = 1E9 Newtons

please show step by step solution. 

Answer 1

Favourite answer

F = (9e9)(6)(19) / 15² = ___ N

or

F = (9)(6)(19) / 225 = ___ GN

Coulomb's law, force of attraction/repulsionF = kQ₁Q₂/r²   Q₁ and Q₂ are the charges in coulombs   F is force in newtons   r is separation in meters   k = 8.99e9 Nm²/C²
