CUET and UG exam CUET UG 2025 Mock Test Series Physics Electric Charges and Coulomb's Law Coulomb’s Law
Two point charges (-q) and (+4q) are placed at separation 'r'. Where should a third charge be placed so that entire system of charges becomes in equilibrium?
1
at separation 'r' from (-q) on the extreme side of -q.
2
at separation 'r' from (4q) on the extreme side of 4q.
3
at separation \(\frac{r}{2}\) from (-q) in between the two charges.
4
at separation \(\frac{r}{4}\) from (4q) in between the two charges.
