1.	A cubical block of mass 'm' rests on rough horizontal surface. mu is coefficient of static friction between block and the surface. A force "mg" acting on cube at an angle " theta" with vertical side of cube pulls the block. If the block is to be pulled along the surface then the value of cot (theta//2) is
Answer» LESS than `MU` greater than `mu` EQUAL to `mu` not dependent on `mu ` ANSWER :B
