A parallel-plate capacitor, at rest in S ₀ and tilted at a 45^? angle to the x₀ axis, carries charge densities }σ₀ on the two plates (Fig. 12.41). System S is moving to the right at speed v relative to S ₀.

(a) Find E₀, the field in S₀.

(b) Find E, the field in S.

(c) What angle do the plates make with the x axis?

(d) Is the field perpendicular to the plates in S?
