Answer:
θ= 131° and in radian rad = 2.27
Step-by-step explanation:
We have find the angle as the tension in the string is 1.20 times the force.
as We have
F = 2.T.cos(θ/2)
Angle can be found as
θ = 2×cos⁻¹(1/(1.2×2))......................2 times because angle between the two halves of the string
θ= 131° and in radian rad = 2.27
