Two conducting spheres of radii R1 and R2 are charged with charges Q1 and Q2 respectively. On bringing them in contact there is :–
- no change in the energy of the system
- an increase in the energy of the system if Q1R2 ≠ Q2R1
- always a decrease in energy of the system
- a decrease in energy of the system if Q1R2 ≠ Q2R1
Answer
(D) a decrease in energy of the system if Q 1 R 2 ≠ Q 2 R 1
