A segment of wire carries a current of 25 A along the x axis from x = −2.0 m to x = 0 and then along the y axis from y = 0 to y
= 3.0 m. In this region of space, the magnetic field is equal to 40 mT in the positive z direction. What is the magnitude of the force on this segment of wire?

Time taken to reach water :
Now, initial vertical speed , u = 0 m/s.
By equation of motion :
Here, a = g = acceleration due to gravity = 9.8 m/s².
So,
Therefore, the height of the bridge is 3.46 m.
Hence, this is the required solution.
