Physics Force & Laws Of Motion Level: Misc Level
A heavy wooden block is dragged by a force e along a rough steel plate, as shown below for cases. The magnitude of the applied force c is the same for both cases. The normal force in (ii) as compared with the normal force in (i) is;
a. the same
d. leass for some angles of the incline and greater for
e. less or greater, depending on the magnitude of the applied force c.
