Question

If the met force acting on a body is zero than acceleration is______

Answer 1

We know, by 2nd law of motion, that,

$F = ma$
That is, Force is equal to product of objects mass and acceleration, and is directly proportional to the Mass and the acceleration of the body. If mass of object is more, the force will be more. Similarly if acceleration of object is more, the force will be more.

So, in this case,

F = 0
Let us suppose that Mass = 10kg and acceleration = a

We have to find acceleration

$F = ma$
$0 = 10\times a$
$= > 10a = 0$
$= > a = \frac{0}{10}$
$= > a = 0$
Hence, the acceleration of the object is 0 m/s².
We can suppose weight to be any other variable. In any of the other cases, the acceleration will be 0.

That's your answer.

Hope it'll help.. :-D
