(50%) Problem i: A uniform electric field of magnitude E 28 N/C points along the x-axis. A circular loop of radius R 18 cm is centered at the origin with the normal to the loop pointing 0 25 degrees above the x-axis Otheexpertta.com 50% Part (a) Calculate the electric flux in units of Nm?IC that passes through the loop A 50% Part (b) To what angle in degrees relative to the x-axis should the normal of the loop be rotated so that the flux through the loop becomes p' 0.34 Nm /C?

a) elctric flux = A*E*cos(theta)
= pi*R^2*E*cos(theta)
= pi*0.18^2*28*cos(25)
= 2.58 N.m^2/C
b) electric flux = E*A*cos(theta)
cos(theta) = electric flux/(A*E)
= 0.34/(pi*0.18^2*28)
= 0.1193
theta = cos^-1(0.1193)
= 83 degrees
