Question

What will be the change in acceleration of a sliding block, if its mass is doubled while a constant force is acting on it ?

Answer 1

we know 

F = ma 
If m = 1 kg and,
   a  = 1 m/s²

Force is said to be 1N 

But if mass is doubled as 2 kg 

The acceleration (a) = F/m = 1/2 

The acceleration will be got reduced to half 

Answer 2

Answer:

Explanation:

Force (f)= m×a

Let us take mass as 1kg and acceleration as 1ms-¹

Therfore,

F =ma =1×1 = 1N

A/Q,

If mass is doubled ,then total mass=1+1=2kg & acceleration =F/m =1/2ms-¹.
