Answer:
F = 0.7 N
Explanation:
As we know that the wire touch the ends of the diagonal of the rectangle
so here the length of the wire is given as
[tex]L = \sqrt{x^2 + y^2}[/tex]
[tex]L = \sqrt{0.6^2 + 0.8^2}[/tex]
[tex]L = 1 m[/tex]
now force due to magnetic field on current carrying wire is given as
[tex]F = iLB[/tex]
now we have
[tex]F = (7)(1)(0.1)[/tex]
[tex]F = 0.7 N[/tex]
