Question

the set of three forces are reacts on a partical.whose last force can not be zero then the forces is-
1.10,10,10
2.10,20,40
3.10,20,10

Answer 1

If the sum of 3 forces equal to zero, force vectors are triangle’s sides.
If forces are 10,20 and 40, they cannot combine a triangle, as one of the side are bigger than the sum of two other sides.
So, answer is (10,20,40)
