Question

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

Answer 1

Answer:

Let the mass of body be m and the force acted on it be f. Hence, when the mass and force on the body is doubled then, acceleration remains same.

Answer 2

EXPLANATION:-

We know that:-

a=f/m-----------1

Now let's double mass and force:-

f=2f

m=2m

Now acceleration=

a=2f/2m

Cancel 2 in numerator and denominator in L.HS,we get:-

a=f/m------------2

SINCE 1 AND 2 ARE SAME SO THEIR IS NO EFFECT ON ACCELERATION IF MASS AND FORCE IS DOUBLE
