A block of mass ๐= 10 kg is lying on an inclined plane PQ. The mass is restrained from sliding down the inclined plane by a force ๐น. The coefficient of friction between the block and the inclined plane is 0.3. Take the acceleration due to gravity as 10 m/s2. The smallest force ๐น (in N) required to prevent the block from sliding down is______(rounded off to one decimal place).
Answer: 23.0 to 25.0
