An infinite line of charge with linear density λ1 = -6.6μC/m is positioned along the axis of a thick conducting shell of inner radius a = 2.7 cm and outer radius b = 4.5 cm and infinite length. The conducting shell is uniformly charged with a linear charge density λ 2 = 3.1 μC/m.

1210 N/m between the inner and outer edges (repulsive)

252.59 N/m between inner and line charges (attractive)

1210+252.59=1462.59 N/m effective force/metre on the inner edge

Explanation:

f=k*Qq/r^2 was applied, the charges are concentrated at the edges of a ring both inner and the outer were shape edges with uniform charge densities 6.6 micro C/m of distance 4.5-2.7=1.8 cm

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
