Question

which law of motion is used? and justify please​

Answer 1

Answer:

THE FIRST LAW OF MOTION IS USED FOR THIS PICTURE SINCE THE FIRST LAW OF MOTION STATES THAT A OBJECT CONTINUOUS ITS STATE OF REST OR UNIFORM MOTION IN A STRAIGHT LINE UNLESS IT IS MADE TO CHANGE ITS STATE OF MOTION BY AN EXTERNAL UNBALANCED MOTION  

IN THE PICTURE THE OBJECT WOULD HAVE BEEN AT REST IF 20 N IS ACTING ON LEFT AND RIGHT

BUT THE NET FORCE IS IS -10 N WHICH MEANS IT MOVES IT IN THE NEGATIVE X AXIS DIRECTION WITH A FORCE OF 10 N

IN THE FIRST LAW OF MOTION FORCE IS DESCRIBED AS AN EXTERNAL UNBALANCED QUANTITY WHICH TENDS TO CHANGE THE STATE OF THE OBJECT FROM REST OR FORM UNIFORM MOTION IN A STRAIGHT LINE
