Answer:
v = 666.667 m/s
Explanation:
<u>Given</u>: length L = 25 cm = 0.25 m, B = 600 G = 0.06 T ( 1G = 0.0001 T)
emf= 10 V
Solution:
emf = vBL
v= emf / BL
v = 10 V / (0.06 T× 0.25 m)
v = 666.667 m/s
Normal force = 200(9.81) = 1962 N
Friction force = 1962 * .4 = 784.8
power = force * distance / time = 784.8 * 5 = 3924 Watts
Watts = Joules / sec
3924 x 180 = 706,320 Joules
