(20%) Problem 1: A uniform electric field of magnitude E-28 N/C points along the x-axis. A circular loop of radius R = 17 cm is centered at the origin with the normal to the loop pointing = 65 degrees above the x-axis ©theexpertta.com 50% Part (a) Calculate the electric flux in units of Nm2/C that passes through the loop?

All content © 2015 Expert TA, LLCExplanation / Answer
(a) Flux = EAcos(theta)=28*pi*0.085^2*cos65=0.269 Nm^2C^-1
(b) Now EAcos(theta)=0.49
cos(theta)=0.49/(28*pi*0.085^2)=0.77
Theta =39.6 degree
