Question

Two charges (Q1 = 0.00368 ; Q2 = 0.00059 ) are separated by a distance of 0.4 meters. What is the Force between them?

Answer 1

Coulomb force

`\tt F=k(q_1.q_2)/(r^2)`

F = coulomb force (N)

Q1,Q2 = the charge (C)

r = distance between two charges (m)

k = constant = 9.10⁹ Nm² / C²

Input the value:

`\tt F=9.10^9(0.00368* 0.00059)/(0.4^2)=122130~N`
