A body moves along a circular path of radius \( 10 \mathrm{~m} \) and the coefficient of friction is \( 0.5 \). What should be its angular speed in \( \mathrm{rad} / \mathrm{s} \) if it is not to slip from the surface \( \left(g=9.8 \mathrm{~ms}^{2}\right) \)
[BHU 2006]
(a) 5
(b) 10
(c) \( 0.1 \)
(d) \( 0.7 \)
