The coefficient of static friction between the block and the plane is 0.8. If the frictional force on the block is 10 N, the mass of the block in (kg) is: (Take g = 10 m/second square)

A block rests on a rough inclined plane making an angle of 30 degrees with the horizontal. The coefficient of static friction between the block and the plane is 0.8. If the frictional force on the block is 10 N, the mass of the block in (kg) is: (Take g = 10 m/second square)

The acceleration of the block is 1) 6 m/s^2 2) 8 m/s^2 3) 10 m/s^2 4) 12 m/s^2
