Supposed that the object is stationary on the floor. In order to lift it up, does it necessary mean that the force to lift the object upwards must be greater than the object's weight?
If force must be greater than the weight to lift an object up, then 2.00000000000000000000000000000001 N will be possible.
As this is a multiple choice question, there is a correct ans. The choice none of the above would be redundant i guess.
I would think that the answer is 4N. As F must be greater than the weight before a resultant force can cause a movement in the desired direction. As to 2N, it only overcome the weight which implies that it is in equilibrium, hence no movement will be made.
Anyone has a different opinion or...
1. A block weighs 2N. What is the force required to move the block up by 2m?
a) 0N
b) 1N
c) 2N
d) 4N
Wanna hear from experienced teachers and personnel on this question.
