Questions
Two equal point charges are kept at a separation of r = 8 cm from each other and potential energy of the system is found to be U. Now 50 % of charge is transferred from one charge to another. What will be the new separation between the charges for which the electrostatic potential energy of the system will be U?
detailed solution
Correct option is D
k⋅Q⋅Qr=U and k⋅3Q2⋅q2r′=U34⋅KQ2r'=KQ2r⇒r′=34r=6cmTalk to our academic expert!
