A block of base 10 cm*10 cm and height 15 cm is kept on an inclined plane.The coeffecient of friction between them is 3^1/2. The inclination α of this inclined plane from the horizontal plane is gradually increased from 0 degree.Then, a) at α=30, the block will start sliding down the plane. b) the block will remain at rest on the plane up to certain α and then it will topple c) at α=60, the block will start sliding down the plane and continue to do so at higher angles d) at α=60, the block will start sliding down the plane and on further increasing α ,it will topple at certain α

a) at α=30, the block will start sliding down the plane.


b) the block will remain at rest on the plane up to certain  α and     then it will topple


c) at α=60, the block will start sliding down the plane and         continue to do so at higher angles


d) at α=60, the block will start sliding down the plane and on further increasing α ,it will topple at certain α
