If \(T_{1}\) and \(T_{2}\) are tensions on tight and slack side of belt, \(\theta\) is angle of contact and \(\mu\) is coefficient of friction between belt and pulley, then ratio of tension is:

(a) \(\mathrm{T}_{1} / \mathrm{T}_{2}=\mu^{\theta}\)

(b) \(\mathrm{T}_{1} / \mathrm{T}_{2}=\mathrm{e}^{\mu \theta}\)

(c) \(T_{1} / T_{2}^{2}=e \mu^{\theta}\)

(d) \(\mathrm{T}_{1} / \mathrm{T}_{2}=\mathrm{e}^{1 / \mu \theta}\)
