Answer:in equilibrium if it is closer to A than to C
in equilibrium midway between A and C
B can never be in stable equilibrium .
in equilibrium if it is closer to C than to A.
Answer :
A::C
Solution :
a.,c.
As A and C are earthed, they are connected to each other. Hence, 'A+B' and 'B+C' are two capacitors with the same potential difference. If B is closer to A than to C, then the capacitance CAB>CBC. The upper surface of B will have greater charge than the lower surface. As the force of attraction between the plates of a capacitor is proportional to Q2, there will be a net upward force on B. This can balance its weight.
