Physics - Elecrostatics Question with Solution | TestHub

A thin rod of length $L$ lies along $X$ axis such that its one end is at origin. The charge density on the rod is given by $\lambda ={\lambda }_0{\mathrm{x}}^2$. The electric field at origin is given by $\alpha \mathrm{K}{\lambda }_0\mathrm{L}$. Write $\alpha$ .
