Negative linear charge density
WebAn electric dipole consists of charges ± 2. 0 × 1 0 − 8 C separated by a distance of 2. 0 × 1 0 − 3 m.It is placed near a long line charge of linear charge density 4. 0 × 1 0 − 4 C m − 1 as shown in the figure, such that the negative charge is at a distance of 2. 0 c m from the line charge. The force acting on the dipole will be WebA long straight wire has fixed negative charge with a linear charge density of magnitude 4.8 nC/m. The wire is to be enclosed by a coaxial, thin-walled, nonconducting cylindrical shell of radius 1.2 cm. The shell is to have positive charge on its outside surface with a surface charge density s that makes the net external electric field is zero.
