Will it move?

Classical Mechanics Level 3

Three forces P , Q , R P,Q , R are created on a particle. For which value of them particle will move?

P = 6 N , Q = 7 N , R = 9 N P=6N , Q=7N, R=9N P = 10 N , Q = 35 N , R = 15 N P=10N, Q=35N, R=15N P = 15 N , Q = 20 N , R = 25 N P=15N, Q=20N, R=25N P = 10 N , Q = 20 N , R = 29 N P=10N , Q=20N , R=29N P = 2 N , Q = 3 N , R = 4 N P=2N, Q=3N, R=4N P = 5 N , Q = 3 N , R = 7 N P=5N, Q=3N , R=7N

It's impossible to make a triangle with the side length 10,35,15.
Sum of vectors of a triangle is 0.

it is pretty easy to figure out the solution as 10,15,30 is the only option that is different then the others... you could have also added an option where the sum of two forces is equal to the last force and all of them act on a straight line on the given point... just saying :)
