The rough surface of a horizontal table
offers a definite maximum opposing force
to initiate the motion of a block along the
table, which is proportional to the resultant normal force given by the table. ForcesF1, and F2, act at the same angle 0 with the horizontal and both are just initiating the sliding motion of the block along the table. Force F1, is a pulling force while the force F2, is a pushing force. F1 > F2 , because
(A) Component of F, adds up to weight to
increase the normal reaction.
(B) Component of F, adds up to weight to
increase the normal reaction.
(C) Component of F, adds up to the
opposing force.
(D) Component of F, adds up to the
opposing force.
