Part A An object cannot remain at rest unless which of the following holds? View Available Hint(s) O O The net force acting on it is zerd. The net force acting on it is constant and nonzero. There are no forces at all acting on it. There is only one force acting on it O Submit Part B If a block is moving to the left at a constant velocity, what can one conclude? View Available Hint(s) re is exactly one force applied to the block O The net force applied to the block is directed to the left. O The The net force applied to the block is zero. There must be no forces at all applied to the blockExplanation / Answer
(A) According to Newton's Law an object remains in the state of rest or uniform motion untill and unless an external unbalanced force acts on it.
so correct option : Net force acting on it is zero.
(B) Block has constant velocity so no net force is acting on it .
so correct option : The net force applied to the block is zero.
(C) Here net force is acting on the right (1N) but by this we cannot conclude any thing about the motion .
correct option: It would be moving to the left or moving to the right or be instantanously at rest .
(D) constant force produce constant acceleration
correct option : Moving with constant non zero acceleration .
(E) We donot know the direction of the given forces so
correct option: cannot have magnitude equal to 5N .
