PhysicsEasysingle choice

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

Options:

Answer:

Solution:

From geometry:

$\cos θ = \frac{3}{5}$

$\sin θ = \frac{4}{5}$

As the sphere is at equilibrium

$T \sin θ = w$

$T = \frac{5 w}{4}$
