Question

That one which has been circled


Plz tommorow is my exam ....fast

Answer 1

Since masses are in ratio 3 : 5.

 Let the mass of the objects be 3x and 5x.

 Let F1 and F2 be the two forces with a1and a2 accelerations. 

F1 = m1a1 = 3xa1 

and F2 = m2a2 = 5xa2

Since F1 : F2 = 5 : 3 , we have

3xa1 : 5xa2 :: 5 : 3 

⇒ a1 : a2  = 5 × 3 : 3 × 3 

⇒ a1 : a2  = 25 : 9 




Now happy bro
