Two conducting spheres are isolated from their surroundings. The radii of spheres A and B are R and R/2, respectively. Initially sphere A has charge Q, and sphere B is neutral. A wire is connected between the sphere. Which of the following gives the final charge on each sphere after equilibrium is reached and provides a statement of reasoning to support this claim ?
QA=Q,QB=0
, because both spheres must create the same electric field at their surface.
QA=Q/2,QB=Q/2
, because both spheres must create the same electric field at their surface.
QA=2Q/3,QB=Q/3
, because both spheres must create the same electric field at
X
their surface.
QA=Q/2,QB=Q/2
, because both spheres must be at the same electric potential.
QA=2Q/3,QB=Q/3
, because both spheres must be at the same electric potential.
