Question

If the net force on an object is zero, what is the acceleration?

Answer 1

The net force acting on the body is zero, the acceleration acting on the object is also zero.

Step-by-step explanation:

Let the two equal and opposite forces acts on an object be, f and f'

The net force acting on the object is given by the relation,

The net force is given by the resultant vector,

`F= \sqrt{f^(2) + f'^(2) + 2 ff' Cos \theta}`

`F= \sqrt{f^(2) - f'^(2) + 2 ff'` (∵ θ = 180)

`F=\sqrt{(f - f')^(2) }`

F = f - f'

Since the magnitude of the forces are equal,

F = 0

Hence, the net force acting on the body is zero, the acceleration acting on the object is also zero.
