A line of positive charge is formed into a semicircle radius R=0.6m(adsbygoogle = window.adsbygoogle || []).push({});

The charge per unit length is given by [tex]\lambda=\lambda_{0}cos\theta[/tex]

The total charge on the semicircle is 12[tex]\mu C[/tex] Calculate the total force on a charge of 3[tex]\mu C[/tex] placed at the centre of the curvature.

The semicircle is like the top half of a circle with center as the origin. The angle [tex]\theta[/tex] is measured from the y axis.

Thanks for the help
