A circular loop of radius R 29 cm is centered at the origin with the normal to the loop pointing θ = 15 degrees above the x-axis.

Answer 1

Vertical-bar E^vector Vertical-bar = 22 N/C radius of loop = 29 cm = 0.29 m theta = 15 degree Electric flux = E^vector middot ds^vector = Vertical-bar E^vector Vertical-bar Vertical-bar ds^vector Vertical-bar cos theta = 22 times (pi (0.29)^2) cos 15 degree = 5.61 Nm^2/C for phi = 0.33 Nm^2/C = > Vertical-bar E^vector Vertical-bar Vertical-bar ds^vector Vertical-bar cos theta = 0.33 = > cos theta = 0.057 = > theta = 86.745 degree

please rate it up thanks :)
