The force ( F = 800i + 200j ) acts at a point A where cables AB, AC, and AD join. What are the tensions in the three cables?
a) ( TAB = √640000, quad TAC = √320000, quad TAD = √640000 )
b) ( TAB = √80000, quad TAC = √40000, quad TAD = √80000 )
c) ( TAB = √720000, quad TAC = √360000, quad TAD = √720000 )
d) ( TAB = √640000, quad TAC = √320000, quad TAD = √800000 )
