Question

A uniform sphere of weight w and radius 3 m is being held by a string of length 2 m and attached to a frictionless wall, as shown in the figure. The tension in the string will be, 5 w 4, 15 w 4, 15 w 6, none of these

MARKS App · Accepted Answer

From geometry: cos ⁡ θ = 3 5 sin ⁡ θ = 4 5 As the sphere is at equilibrium T sin ⁡ θ = w T = 5 w 4
