Answer:
0.1675 A
Explanation:
Since then making I the subject where L is the length of the rod, in this case given as 1.0792 m, B is magnetic field which is given as 2.88578 T, m is the mass which is 53.1794 g which is equivalent to 0.0531794 Kg . For minimum current,
Substituting the given values then
