According to Coulomb's Law, electro- static force on charge q due to +2e charge is
Where r = 0-(-1)= 1nm= 10^-9 m
Now,
Or, F1 = 18×( 10^27)×(qe) N
Electrostatic force on q due to Q is
Where r = 4-(-1)= 5 nm
Or, (9/25)×(10^27)×(qQ) N
Given that , the net force on q is zero.
So, F1 + F2 = 0
[18×(10^27)×(qe) ] + [( 9/25)×(10^27)×(qQ)]=0
Or, [18×(10^27)×(qe)] = -[ (9/25)×(10^27)×(qQ)]
So, the option -50e is correct answer.
