I don't think so koi formula hai.. We can solve by using the concept that 15cm par half of the distance hoga aur us se thora age ja kar close to the small charge E=0

sir nay bola mid may half hoti hay wesay mera bhi yeh wrong hogaya

Equation bna kr solve kre. As they are not identical charges to midway me to nai hoga. q1 zyada strongly repel krega Q ko islye Q q2 ke zyada qareeb hoga. F1=F2 ki equation bnae qk net force zero honi chahye. Charge q1 ka Charge Q tak ke distance ko "x" suppose krle. q2 ka Q se distance (30-x) hoga. As we know F=kq1q2/r². F1 k liye formula kq1Q/x² hoga. F2 k liye kq2Q/(30-x)² hoga. F1=F2. Values put krlein.
