Explanation / Answer

Part B)Magnitude of electric field = E = 7600 N/C (its a mistake in the question that they wrote magnetic field instead of electric field)

theta = 34 deg ; radius of the disk = r = 4.7 cm = 0.047 m

Area = A = pi r^2 = 3.14 x 0.047^2 = 6.94 x 10^-3 m^2

We have, flux = phi = E A cos(theta)

phi = 7600 N/C x 6.94 x 10^-3 m^2 x cos34 = 43.73 N m^2/C

Hence, phi = 43.73 N m^2/C

Part C)It will be:

Phi = E A cos(theta)

Phi = 7600 N/C x 6.94 x 10^-3 m^2 x cos26 = 47.71 N m^2/C

Hence, phi = 47.71 N m^2/C
