Answer:2.65 A
Explanation:
Given
Length of wire [tex]L=25\ cm[/tex]
mass of wire [tex]m=90\ gm[/tex]
Magnetic field [tex]B=1.33\ T[/tex]
Force on wire due to magnetic field
[tex]F=BiL[/tex]
Force due to magnetic field will balance the weight of wire
[tex]F=mg[/tex]
[tex]BiL=mg[/tex]
[tex]1.33\times i\times 0.25=0.09\times 9.8[/tex]
[tex]i=2.65\ A[/tex]
