NEET Physics Electric Flux MCQ Question

Consider a right circular cylinder of length 20 cm and radius 5 cm with its axis along the x-axis, centered at the origin. An electric field is uniform and in the positive x direction for positive x, and uniform with the same magnitude but in the negative x direction for negative x. If E = 200 $\hat{i}$ N/C for x > 0 and E = -200 $\hat{i}$ N/C for x < 0, what is the total electric flux through the curved surface of the cylinder?
