In this question we are given that a fish is being weighed using the two springs.
00:05
Alright, one is this, another is this and this was the fish.
00:12
This is of 8 kilogram mass.
00:16
So we need to calculate what we were reading in both the springs.
00:19
So first of all the let us draw the free body diagram of all the elements involved.
00:24
So spring one, spring two and fish.
00:27
So for spring one, let us say this is the tension force in the spring and this is the tension force in the spring because the spring has to be balanced like this for the second one let us say this is the force t2 in the spring and this is force t2 for the for the fish sorry upward force this would be the t2 and downout force will be the weight of this so we could clearly say that this t2 is equal to 80 because this fish has to be balanced these both of them has to be equal t2 why? because horses across a spring has to be same because force acting in the spring is k into x and x is what? the displacement or the change in length of the spring from its actual length that is same for a particular spring either it is in one direction or the other.
01:38
Also this t is where this is over here and this t2 is where this 2 is over here.
01:44
These are the same part of a rock or a wire or whatever they are connected with.
01:52
They are same thing.
01:55
So tension, these two tensions would be same.
01:58
So t1 would be equal to you.
02:00
We can clearly say that both the springs will read, will read 80 newton.
02:14
80 newton means 80 by g, g is 10...
