Answer:
10 , 20 , 40
Explanation:
Following set of three forces act on a body whose resultant cannot be zero
(A)10,10,10
(B)10,10,20
(C)10,20,23
(D)10,20,40
D is the right option
10 , 20 , 40
to have the resultant zero
sum of any two vector >= third vector
10 , 20 , 40 does not satisfy this
what you can say about Option (C). Do you thinks its wrong. No Its also Correct. 10, 20 and 23 cannot give zero resultant.
Correct it.
10 20 , 23 can give zero
23^2 = 10^2 + 20^2 + 2*10*20Cosx. => cosx = 29/400 => x = cos-1(29/400) x is the angle between vector 10 & 20 angle approx 4.15 deg
