Question
A semicircular disc of radius "R" carries a charge "Q" distributed non-uniformly over its surface. It is centered at the origin of the x-y-z coordinate system. The disc lies in the y-x plane The surface charge density is given by a*sin(theta), where a is constant with units of coulumbs/m^2 and (theta) is measured off the y-axis. Assume the potential is zero at infinity
Determine the constant "a" in terms of "Q" and "R"
Determine the potential at a point "P" along the x-axis
Find the Electric Field along the x-axis
Explanation / Answer
a=Q/(2R^2)
