Q.3.(a) A block in the shape of a rectangular solid has a cross-sectional area of 3.50 cm' across its width, a front-to-rear length of 15.8 cm, and a resistance of 935 0. The block's material contains 5.33x10 conduction electrons/m. A potential difference of 35.8V is maintained between its front and rear faces. () What is the current in the block? (ii) If the current density is uniform, what is its magnitude? What are (m) the drift velocity of the conduction electrans and (iv) the magnitude of the electric field in the block?
