JEE MainPhysicsElectrostaticsMCQ+4 / −1
Two isolated conducting spheres S1 and S2 of radius 23R{2 \over 3}R32​R and 13R{1 \over 3}R31​R have 12 μ\muμ C and –3 μ\muμ C charges, respectively, and are at a large distance from each other. They are now connected by a conducting wire. A long time after this is done the charges on S1 and S2 are respectively :
  1. A
    4.5 μ\muμ C on both
  2. B
    +4.5 μ\muμ C and –4.5 μ\muμ C
  3. C
    6 μ\muμ C and 3 μ\muμ C
  4. D
