355777 A particle is made to move from the origin in three spells of equal distances, first along the \(x\)- axis, second parallel to \(y\)-axis and third parallel to \(z\)-axis. One of the forces acting on it has constant magnitude of 50 \(N\) and always acts along the direction of motion. Work done by this force in the three spells of motion are equal and total work done in all three spells is 300 \(J\). The final coordinates of the particle will be:

1 \((2,2,2)m\)
2 \((4,4,4)\)
3 \((6,6,6)m\)
