A sofa, ABCD, is placed on a slippery surface. Two forces of 5 N are applied on AD and CD. Tap on the direction in which the sofa will move.
A block needs 50 N of force to move it and you are applying 5 N of force on that block in the horizontal direction. So how much frictional force will the surface be applying on the block?
Two blocks of equal masses m1=m2=3 kg, connected by a light string, are placed on a horizontal surface which is not frictionless. If a force of 20 N is applied in the horizontal direction on a block, the acceleration of each block is 0.5 ms−2. Assuming that the frictional forces on the two blocks are equal, the tension in the string will be
Two blocks of mass 4 kg and 6 kg are placed in contact with each other on a frictionless horizontal surface. If we apply a push of 5 N on the heavier mass, the force on the lighter mass will be
