Answer 1

constant as force is zero means acc is zero and velocity is constant hence momentum is constant.

Answer 2

Answer : constant.

Because from upside downwards 4N + 4N = 8N

Downwards upside 8N

Leftside right onwards 5N + 5N = 10N

rightside left onwards 10N

8N =  8N

10N = 10N

therefore the body is constant.
