Two unlike charges separated by a distance of 1m attract each other with a force 0.108N. If the charges are in the ratio 1:3, the weak charge is?A. 2 micro C ,B. 4 micro C, C. 6 micro C, D. 5 microC

Here q1:q2=1:3,


we know F=k(q1q2)/(r2)

where k=9x109N-m2/C2

thus 0.108=9x109(3(q2)2)/12


therefore the weak charge is 2micro C.

i think it is 2 microC

let charges be x,3x;


f=3x*x*9*10^9          =>x= 2 micro

The answer is 4 micro C. But it could be wrong.
