Please help with parts 1, 2 and 3

± Motional EMF in a Conducting Rod

Part 1

When the charges in the rod are in equilibrium, what is the magnitude E of the electric field within the rod?

Express your answer in volts per meter to at least three significant figures.

Part 2

What is the magnitude Vba of the potential difference between the ends of the rod?

Express your answer in volts to at least three significant figures.

Part 3

What is the magnitude E of the motional emf induced in the rod?

Express your answer in volts to at least three significant figures.

Explanation / Answer

q*v*B = q*E
E = v*B
E = 6*0.540 = 3.24 V/m

Vba = v*B*L

= 6 *0.540 * 0.26

= 0.8424 V

same as part 1
