Question

A manufacturer claims that a carnet will not generate more than 5.0 kV of static electricity. What magnitude of charge would have to be transferred between a carpet and a shoe for there to be a 5.0-kV potential difference between the shoe and the carpet. Approximate the shoe and the carpet as large sheets of charge separated by a distance = 1.0 mm (II) A uniform electric field E = -4.20 N/Ci points in the negative x direction as shown in Fig. 23-25. The x and y coordinates of points A, B, and C are given on the diagram (in meters). Determine the differences in potential (II) The electric potential of a very large isolated flat metal plate is V_0. It carries a uniform distribution of charge of surface density sigma (C/m^2), or sigma/2 on each surface. Determine V at a distance x from the plate. Consider the point x to be far from the edges and assume x is much smaller than the plate dimensions.

Explanation / Answer

the potential difference across the point BA and A is same because they have same potential

V_BA = 0

the E at both the points is same ;

the potential difference across the point CB is

V_CB = V_C - V_B = - E . dl = - ( -4.20 ) * ( -3 cm - 4 cm ) =- 0.294 V

since B and A are at the same potential ; so

V_CA = V_CB =- 0.294 V
