Question

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/are correct? a. N → + T → + W → = 0 b. T 2 = N 2 + W 2 c. T = N + W d. N = W tan ⁡ θ, a, b, c, b, c, d, a, b, d, a, b, c, d

MARKS App · Accepted Answer

As the object is in equilibrium, the net force is zero N → + T → + W → = 0 Also from the diagram, T 2 = N 2 + W 2 From components, N = W tan ⁡ θ
