Question

4s fit (on) G C 4. For given C1, C2, and Cg capacitors, the left figure gives a set of charge-potential difference measurements. The solid line is for G. The dashed lines belong to C2 and C3, respectively. The vertical scale is set by 9.-24.0 uc, and the horizontal scale is set by V=3.0 V. And, some modifications are made in the capacitors: (1) an infinitesimally thin V, metallic slab is inserted into C, (2) a metallic V (V) slab to fill one-fifth of the space without touching the plates is inserted into C2, (3) a dielectric material of x = 5 to fill one-fourth of the plates, where one-plate is touching the dielectric material, is inserted into Cg. Later, a circuit as shown in the right figure is installed with these capacitors. What charge is stored on Cg if the potential difference between points a and bis 30.0 V. 5. A piece of platinum, turned into a long and one end narrowing cylinder, see the figure. The cylinders radius varies with r = ro + ax where a is a constant, x is the distance measured from the narrow end of the shrinking cylinder. Find an expression for resistance of this conductor R: tym al
