Laws of Motion question

2022 · 27 Jun · Shift 2 · Q63

JEE MainPhysicsLaws of MotionNumerical+4 / −1
A mass of 10 kg is suspended vertically by a rope of length 5 m from the roof. A force of 30 N is applied at the middle point of rope in horizontal direction. The angle made by upper half of the rope with vertical is θ\thetaθ = tan −-− 1 (x ×\times× 10 −-− 1). The value of x is ‾\underline{\hspace{2cm}}​. (Given, g = 10 m/s2)
