Gauss' law of electrostatics state that the total of the electric flux out of a closed surface is equal to the charge enclosed decided by the permittivity i.e., electric .
Thus, electric flux through a surface doesn't depend on the shape, size or area of a surface but it depends on the number of charges enclosed by the surface.
So, here in this question, all the figures same electric flux as all of them has single positive charge.

7. A 8 cm-diameter horizontal water jet, having a velocity of 45 m/s, strikes a curved plate, which deflects the water 180° at the same speed. Ignoring the frictional effects, determine the force F required to hold the plate against the water stream. (15 pts) From Reynold's theorem, the following equation is obtained for a jet of fluid: F = ρv₁cosθ, where θ is the angle of deflection.

Problem 8.2 (a) Consider a linear polarizer and a wave linearly polarized at an angle θ with respect to the polarizer's transmission axis. Show that the intensity of the wave is reduced by cos^2 θ after passing through the polarizer (this is called the Law of Malus). (b) Consider a system of N cascaded polarizers. The polarizers have their transmission axes at angles π/2N, 2π/2N, 3π/2N, ..., 7π/2N from the x-axis, in the order that an input wave sees them. That is, the last polarizer is oriented along the y-direction. Suppose that an input wave is polarized in the x-direction. Compute the intensity transmission coefficient for the system. Show that the transmission coefficient approaches unity as N → ∞. This is a simple realization of the quantum Zeno effect, where each polarizer acts as a "measurement" of the polarization state - the polarization is "dragged" by the measurements as long as they are sufficiently frequent. Note that it isn't sufficient to merely argue that cos(π/2N) → 0 as N → ∞, because the interplay of the cosine with the exponent is nontrivial. In particular, it is critical that the first-order term in 1/N vanishes for the cosine, while the exponent scales as N. For example, if the exponent scales more quickly with N, lim N → ∞, then we can have convergence to other values. (8.55) 2N

The block lands on the spring and then compresses it a maximum amount d. Find an expression for the speed of the block when the compression of the spring is d/2. The expression should be in terms of h, k, d, m, and g.
