Question

A uniform charged infinite straight line having linear charge density lambda ,is passed through the Centre of a sphere . R is the radius of the sphere . The electric flux through the sphere is given by

Answer 1

Dear Student,


Let the length of the rod be L
for L=2R
Thus total charge of the rod=$2\lambda R$
According to gauss law total electric flux through a closed surface=$\frac{Q_{enc}}{{\epsilon }_0}\Rightarrow \frac{2\lambda R}{{\epsilon }_0}$

Regards.
