A block of mass $5\,kg$ and surface area $2\,m ^2$ just begins to slide down an inclined plane when the angle of inclination is $30^{\circ}$. Keeping mass same, the surface area of the block is doubled. The angle at which this starts sliding down is :
- A$30^{\circ}$
- B$60^{\circ}$
- C$15^{\circ}$
- Dnone
