A body of mass 40 gm is moving with a constant velocity of 2 cm/sec on a horizontal frictionless table. The force on the table is
39200 dyne
160 dyne
80 dyne
Zero dyne
The correct option is A
39200 dyne
Force on the table will be the weight of body i.e. W = mg
Value of g=980 cm/s2
Force on the table =mg=40×980=39200 dyne
