A string (A) hanging from the ceiling has a 1 kg mass attached to it and hanging below this mass is string (B) with a 2 kg mass attached. Both of the strings are massless.

How do I calculate the tension in Cord B?

  • physics -

    Schematically, it looks like this (turned 90 degrees)


    The only mass string B is supporting is the 2kg mass. So the tension in string B is
    =2kg * g
    =2*9.8 N
    =19.6 N.
