Question

Part A A disk with a radius of R is oriented with its normal unit vector af an angle 0 with respect to a uniform electric field. Which of the following would result in an increase in the electric flux through the disk? Check all that apply decreasing the given onientation angle of the disk increasing the given orientation angle of the disk, but not exceeding an angle of 90 decreasing the strength of the electric fieid Oincreasing the strength of the electric teld decreasing the area of the dek increasing the area of the disk Submit

Answer 1

answer) we know the formula

$\phi$( flux)=EA cos$\Theta$

so the correct options are-1)increasing the strength of electric field, 2) increasing the area of the disk, 3) decreasing the given orientation angle of the disk

since flux is directly proportional to area and electric field according to the above equation and we know that the value of cos$\Theta$ decreases as the value of $\Theta$ increases , so smaller the angle more will be the value of cos$\Theta$ and since its proportional to flux , the flux increases.
