✔ 最佳答案
Given,
Charge (Q) = +3.56*10-6C
Charge (q) = -1.93*10-6C
K (constant) = 8.99*109Nm²/c²
Force (F) = 0.292N
Distance between two point charges (r) =?
We know that:-
From Coulomb’s law:-
F = KQq/r²
0.292 = 8.99*109*(3.56*10-6)*(-1.93*10-6)/r²
0.292*r² = +8.99*109*3.56*1.93*10-12
R2 = +8.99*109*3.56*1.93*10-12/0.292
R2 = +211.5359*10-3
R = √211.5359*10-3 = 0.459m
R = 0.459m
Distance between two point charges = 0.459m
