A block of mass m resting on a rough horizontal table (co-efficient of friction = µ) is pulled by a force F as shown in the figure. The acceleration of the block moving horizontally is
1
\(\frac{{Fcos\theta }}{m}\)
2
\(\frac{F}{m}cos\theta - \mu g\)
3
\(\frac{F}{m}\left( {cos\theta + \mu sin\theta } \right) - \mu g\)
4
\(\frac{F}{m}\left( {cos\theta - \mu sin\theta } \right) - \mu g\)
