Question

5. The masses of two bodies are in the ratio of 3:4. On applying a certain force on the first
body, an acceleration of 6 m/s is produced. What will be the acceleration in the second body
when the same force is supplied on it
​

Answer 1

Answer:

let the mass of the two bodies be 3x and 4x and force be f and acceleration of the 2nd body be y then

force = mass × acceleration

for 1st body

f = 3x × 6

f = 18x

again for 2nd body

force = mass × acceleration

f = 4x × y (as force are same in both conditions)

18x = 4x × y

y = 18x/4x

y = 4.5 m/s^2
