The correct option is B (1, 11)
As explained vividly in the videos,
"The Linear momentum of a system remains constant in magnitude and direction, if the external forces acting on the system add up to zero.”
Utilizing the principle of law of conservation of linear momentum as there is no net External force on mentioned objects,
→Pl=→Pf
→(Px)i=(Px)ialso(Py)i=(Py)i
-4 + b = 3 + 4 5 - 2 = a + 2
b = 11 a = 1
(1,11) is the correct option.
