A metal sphere is hung by a string fixed to a wall. The sphere is pushed away from the wall by a stick. The forces acting on the sphere are shown in the second diagram. Which of the following statements is wrong?
detailed solution
Correct option is D
As the metal sphere is in equilibrium under the effect of three forces therefore T→+P→ +W→ = 0From the figure T cosθ = W----(i) Tsinθ = P ----(ii)From equations (i) and (ii), we getP = W tanθand T2 = P2+W2Talk to our academic expert!
