Two charged di electric spheres A solid and B hollow of same radius R and masses 2m and m respectively are kept on a horizontal rough surface The two spheres A and B have charges 2Q and Q respectively and uniformly distributed They are released from rest when their centres are separated by very large distance Assuming there is no sliding List I Sold EXXT P Kinetic energy of system just before A and B meet Q Kinetic energy of A just before A and B meet R Kinetic energy of B just before A and B meet Codes P A 2 B 1 C 3 S Rotational kinetic energy of system just before A and B meet 1 R 1 2 List II 838kQ 2345R kQ R 25kQ 67R 42kQ 67R
