A body of mass 40 gm is moving with a constant velocity of 2 cm/sec on a horizontal frictionlessforce on the table is-(1)39200 dyne(3) 80 dyne(4) zero dyne(2) 160 dyne |

Answer» Force on the table is given by F =mg=40 x 980=39200 dynes Zero dyne because in ques. they mentioned that it moving with const.velocity therefore acc. is zero so force = 0 dyne |
