Questions
A metal sphere is hung by a string fixed to a wall. The forces acting on the sphere are shown in figure. Which of the following statements is NOT correct?
detailed solution
Correct option is C
As the body is in equilibrium, so vector sum of all three forces N→, T → and W→ should be zero. Hence (a) is correct. NowT sin θ = N ----(1)T cos θ = W -----(2)(l)+(2) ⇒ tan θ = NW⇒ N = W tan θ. Hence (d) is correct.Squaring and adding (1) and (2); T2 = N2+W2Hence (b) is correct.Hence (c) is incorrect.Talk to our academic expert!
