Hi Pallavi,


As one charge is + and other is -ve definitely the third charge should be negative as the negative charge has less magnitude compared to + ve charge.


third charge should be on the the line joining the two charges.


it should be away from + ve and closeer to - ve.


it sholud not be in between the two.


then let third charge be x distance from -ve charge then it will be at 10+x from + charge.


|F1|=|F2|


2*q/(10+x)2=1*q/(x)2


2x2=100+x2+20x


x2-20x-100=0


x=10±10√2 = 10+10√2
