The track lies in a vertical uniform magnetic field of magnitude 3.03 T. At time t 0, device G is connected to the rails, producing a constant current i = 0.150 A in the wire and rails (even as the wire moves). At t = 4.00 s what is the wire's speed and direction of motion? Take positive to the right and negative to the left. d/ B 1.2423 m/s Submit Answer Incorrect.

Explanation / Answer

F= iL X B,

In this case all are perpendicular

so, F = iLB

whrere i = 0.150 A

L = 0.410 m

B = 3.03 T

F = 0.150 x 0.410 x 3.03

F = 0.186 N

Now, F = ma

m = 0.600 kg

so a = F/m

a = 0.186 N / 0.600 kg

a = 0.310 m/s^2

speed is v = a*t

at t = 4 sec

v = 0.310 m/s^2 x 4 s

v = 1.2423 m/s

The direction is to the left away from the generator G
