Question

Part B and C Please

The parallel-plate air capacitor in the Figure (Figure 1) in the textbook consists of two horizontal conducting plates of equal area A The bottom plate rests on a fixed support, and the top plate is suspended by four springs with spring constant k , positioned at each of the four corners of the top plate as shown in the figure. When uncharged, the plates are separated by a distance z 0. A battery is connected to the plates and produces a potential difference V between them. This causes the plate separation to decrease to z . Neglect any fringing effects. Figure 1 of 1

Part B Given the values A = 0.300 m 2 , z0 = 1.20 mm , k = 25.0 N/m N/m , and V =120 V , find the two values of z for which the top plate will be in equilibrium. Give the answers in ascending order separated with comma.

Part C For unstable equilibrium, a small displacement gives rise to a net force that takes the object farther away from equilibrium. For which value of z found in part B, is the equilibrium stable?
