Express your answer with the appropriate units. Value Units Subm My Answers Give Up Contin Provide Feedback

Explanation / Answer

B = 0.510 T
v =  1.82*10^6 m/s

In Velcoity selector,
Electric Force = Magnetic Force
q*E = q*v*B
E = v*B
E = 1.82*10^6 * 0.510 V/m
E = 9.28 * 10^5 V/m

Potential Difference, V = E.d
V =  9.28 * 10^5 * 5.2 * 10^-3 V
V = 4825.6 V
