Asinusoidal beam of electromagnetic radiation that is only 2 cm high propagates in the +x direction, with the electric field in the ±z direction. the beam strikes a metal rod that is centered on the origin and aligned along the z axis.
you place detectors sensitive to electromagnetic radiation at location ⟨0,−17,0⟩ m (detector a) and location ⟨0,0,17⟩m (detector b).

answer the following questions for detector a and for detector b: will the detector detect electromagnetic radiation?

if so: what is the direction of the magnetic field in the radiation?

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.
