A) First it will move with a constant velocity for some time and then will have accelerated motion
B) the block move having accelerated motion over the surface
C) The block move over the surface with a constant velocity
D) The block will not move
Correct Answer: D
Solution :
Since, the force of 3.5 N will keep the block in uniform motion it means no net force will act on the body as the applied force of 3.5 N is just sufficient to overcome the force of friction. If the force applied is less than 3.5 N the block will not move. Hence, when 3N is applied, block will not move.You need to login to perform this action.
