Two bodies have masses in the ratio3:1. They experience forces which impart to them, acceleration in the ratio 2:9 respectively. Find the ratio of forces the masses experienced
1:4
2:1
2:3
2:5
Correct answer is C
Given m1m2=31 ⇒ m1 = 3m2
a1a2=29 = a1 = 2a29
F1F2 = ?
Since F = ma
⇒ F1F2=m1a1m2a2 = (3m̸2)(2a̸2)m̸2a2a̸3
F1F2=23 ⇒ 2:3
