Answer:
67.17°
Explanation:
From the question,
F = BILsinФ............. Equation 1
Where F = force on the wire, B = magnetic field, I = current carried by the wire, L = length of the wire, Ф = angle between the wire segment and the magnetic field.
make Ф the subject of the equation
Ф =sin⁻¹ (F/BIL)............... Equation 2
Given; F = 0.26 N, B = 1.24, I = 0.35 A, L = 65 cm = 0.65 m
Substitute into equation 2
Ф = sin⁻¹[0.26/(1.24×0.35×0.65)]
Ф = sin⁻¹(0.26/0.2821)
Ф = sin⁻¹(0.9217)
Ф = 67.17°
