The Attempt at a Solution
[/B]
Initially , let the tension in spring be T
Since hanging mass is just touching the weighing scale , T = 5g
When elevator starts to accelerate upwards with acceleration 'a' , then on applying a fictitious force '5a' downwards and doing a force balance on the mass
T + N = 5g + 5a
N is the normal force from the weighing machine and T will not change
So, N = 5a
I am getting D) I.e data insufficient ,but this is incorrect .
Given answer is B) .
What is my mistake ?
