Question

If mass of an object is doubled and force acting on it is halved.What would happen to it's acceleration?​

Answer 1

Answer:

Then its acceleration will be decreased.

Answer 2

ANSWER : The ans is : a' = 1/4a

EXPLANATION :

We know that Force(F) = Mass(m)*Acceleration(a)

=> a= F/m

At 1st case, a =F/m ......(i)

Now, when the force is halved and mass is doubled,

acceleration' = F/2*2m

a' = F/4m ......(ii)

Comparing (ii) by (i) we get:

=>a'/a= F/4m by F/m

=> a'/a= F/4m *m/ F

=> a'/a= 1/4

=> a'=1/4a

Hence, the answer is a' = 1/4a
