**Answer:**

ANS. 8 : 15

**Explanation: Suppose the two masses of car (m1) and (m2) are in the ratio 4:5 and having the acceleration (a1) and (a2) in the ratio 2:3 respectively. **

**Wehave the formula, F = ma **

**So applying the above formula for the both cars we get,**

**F1 = m1 .a1 ---- (a)**

**F2 = m2 .a2 ----(b)**

**Divide (a) by (b) , we get ,**

** = ** *

Putting the values we get,

F1 : F2 = 8 : 15 ans.
