Question

if the mass of a body and the force acting on it are both doubled,what happens to its acceleration

Answer 1

Heya!

Let the mass of body be m and the force acted on it be f.

Then,

Since, f = ma

=) a1 = f/ m .......(i)

______________________

Now,

When they are doubled,

2f = 2 m* a2

=) a2 = 2f/2m .............(ii)

Comparing eq (i) and (ii)

a1/a2 = (f/m) / ( 2f / 2m)

=) a1/a2 = ( f * 2m) / ( m * 2f)

=) a1 / a2 = 1 / 1

Hence, when the mass and force on the body is doubled then, acceleration remains same.

Hope it helps u.

Answer 2

Answer:

Explanation:

If both are doubled then ,

The acceleration at that time remain the same.
