A block of mass \(m\) rests on a horizontal table with a co-efficient of static friction \(\mu\). What minimum force must be applied on the block to drag it on the table ?
(A) \(\frac{\mu}{\sqrt{1+\mu^{2}}} \mathrm{mg}\)
(B) \(\frac{\mu-1}{\mu+1} m g\)
(C) \(\frac{\mu}{\sqrt{1-\mu^{2}}} \mathrm{mg}\)
(D) \(\mu \mathrm{mg}\)
Ans(C)
