Answer 2

Answer:

(i) 7.2

Explanation:

so the whole rod is 1 m long.. and the question says that the pivot is in the centre... so half side is 50 and the other half is also 50

so the question says to the left side the force 12N clockwise and the distance is 30...

so now you use the formula f1*d1=f2*d2

so 12*30=S*50

  360=50s

  360/50=s

  7.2=s
