In this problem, we are given that there is a system which consists of two blocks.
00:07
One is 2kg block and the other one is 6kg block and this is connected by a light inextensible string passing through the pulley.
00:17
And we are required to determine the acceleration of the system provided that the system is released from rest.
00:25
So here the acceleration of both these blocks, that will be same because they are connected.
00:30
And let's take the acceleration in the downward direction, which is the most preferred case here.
00:37
And let's draw the free body diagram of each of the blocks.
00:40
So for 6kg block, there will be weight, and we will use this expression to get the weight.
00:45
According to this, the weight is mass times the acceleration due to gravity.
00:49
And there will be tension force.
00:51
And if we look at this 2kg block, there will be just tension force.
00:55
And now we will apply this equation, which is in accordance with newton's second law of motion...
