Question

A body of mass 40 g is moving with constant velocity of 2 cm/sec on a horizontal frictionless table. The force on the table is : (A) 160 dyne (B) 39200 dyne (C) 80 dyne (D) zero

Body is moving with constant velocity, it means there is no acceleration, so from Newtons 2nd law F=ma, a=0, so no force acts.
