before see the explanation,i i am zerone_son( the legendary from brainly user is back)

Penjelasan:

dik=  

Qa1 = 2q

Qa2 =-3q

Ra  =  d

Qb1 =-q

Qb2 = 4q

Rb = 1/2d

Fa = F

DIT = Fb......?

Fa/Fb = ((k*Qa1*Qa2)/(Ra)^2) / ((k*Qb1*Qb2)/(Rb)^2)

Fa/Fb = ((2q*3q)/(d^2)) / ((q*4q)/(1/2d)^2

Fa/Fb = (6q/d^2) / ((4q /(1/4d))

F /Fb= 6q / 4*4q

Fb = 16/6 *F

Fb = 8/3F

note= the negative from the question has not problem to this answer because (negative hanya berlaku untuk mengetahui muatan yang bernilai negatif saja)
