So in this question we have connected two police with mass.
00:05
So the free body diagram for the masses of 1 kg and 2kg can be drawn like this.
00:10
So this is 1kg mass and this is 2kg mass and the weight will be 1g and this will be 2g.
00:18
Now the tension will be t and t here and now this complete frame is moving with an acceleration g by 4.
00:26
Okay, which is in the downward direction.
00:29
So this is g by 4.
00:30
So the pseudo -acceleration will be act on this a block as g by 4 and on it, it will be 2g by 4.
00:39
And suppose the acceleration of block a, this is our block a.
00:43
So acceleration is a.
00:44
So we can write the equation of motion for the block a.
00:47
So we can write that for block a for a.
00:52
This is a and this is block b.
00:54
So we can write for the equation of motion that acceleration is in the upper direction...
