The figure shows four pairs of parallel identical conducting plates, separated by the same distance 2.0 cm and arranged perpendicular to x-axis. The electric potential of each plate is mentioned. The electric field between a pair of plates is uniform and normal to the plates.
Let \(V_0\) be the potential at the left plate of any set, taken to be at \({x}=0 {~m}\) . Then potential V at any point \((0 \leq {x} \leq 2 {~cm})\) between the plates of that set can be expressed as:
where \(\alpha\) is a constant, positive or negative.
- \(V=V_0+\alpha x\)
- \(V=V_0+\alpha x^2\)
- \(V=V_0+\alpha x^{1/2}\)
- \(V=V_0+\alpha x^{3/2}\)
Answer
(A) V=V_0+ x
