Answer:
Explanation:
Wire is in the form of an arc of the size of a quarter of a circle. The distance between its two end
=√2 x 21 cm
= 29.7 cm
= 29.7 x 10⁻² m
Force on the arc in the magnetic field will be same as the straight line meeting its two ends.
Force = BIL
= 48 x10⁻³ x 1.5 x 29.7 x 10⁻²
= 2138.4 x 10⁻⁵ N.
