1.	A cubical block of mass 'm' rests on rough horizontal surface. muis 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
