Some Particular Forces

  1. Oct 23, 2006 #1
    A block with a weight of 3.0N is at rest on a horizontal surface. A 1.0N upward force is being applied to the block by means of an attached vertical string. What are the magnitude and the direction of the force of the block on the horizontal surface? I was wondering what it meant by the attached vertical string, is the string attached to the top of the block and then to a ceiling?

    Yes, that makes sense.

    This seems like a very easy problem, if I'm approaching it properly. You would have your 3.0N down as your mg and the T would be 1.0N up. Would that mean that the megnitude would be 2.0N downward as a final answer?

    Yes, that is the correct answer.

    Sadly, I can't help about the conversion question, but I'm 100% sure that you could google-up an answer in any time.
