Answer
Correct option is A 2:5
Explanation:
Now acceleration will be different in the two masses They will be F/2 and F/5
Let v be the same velocity attained by them starting from rest
So using v = u + a t
V1 = F/2 ×T 1
V 2 = 4 F ×T 2
Given v 1 =v 2
F/2 ×T 1 = F/5 ×T 2
=2:5
PS; This is the correct answer of the Question: Consider two bodies with masses 2kg and 5kg respectively. Both the bodies are at rest and the same force is acting on both the bodies. What is the ratio of times that is required to reach a final velocity?
