A Potential Difference of V = 0 $\varOmega$ MThe Dimensions of the Si Block Are: Width 1

A potential difference of V = 0.500 V is applied across the length of a rectangular block of silicon (Si) with resistivity 8.70 *10^-4 $\varOmega$ m.The dimensions of the Si block are: width 1.50 mm;thickness 0.400 mm;and length L = 20.0 cm.You may assume that the current density in the Si block is uniform and that currents in Si obey Ohm's law.What is the resistance of this Si block?

A) 92.3 $\varOmega$
B) 362 $\varOmega$
C) 78.4 $\varOmega$
D) 290 $\varOmega$
E) 452 $\varOmega$
