  1. VA=VB=VC
  2. VA=VB>VC
  3. VA>VB=VC
  4. VA=VB<VC

A
VA=VB<VC
B
VA=VB=VC
C
VA=VB>VC
D
VA>VB=VC
Solution
Verified by Toppr

As we know the electrical lines of force always travel from higher potential to lower potential and lines of forces are perpendicular to the equipotential surface. So, VA=VB and VB>VC
