Hello students an object of mass m is placed on the table and frictionless table which is inclined.
00:07
Now they are asking about for the first question if the net force acting on the block is always zero.
00:16
No, the net force acting on the block is not zero, not zero.
00:32
Therefore f net is not equal to zero per block because there is a gravitational force force on downwards and there is no counter force on it therefore the net force on block is not equal to zero therefore the answer for the first question is equal to f net on block is not equal to zero for the second question it is asked that does the net force on the incline f net on the incline is 0 is always 0.
01:37
No, the net force on the incline is not always 0.
01:43
F net on incline is not always 0 because the gravitational force is acting on the object and the incline should not have the net force always 0.
01:59
Now for the third question it is asked that the net force on the block incline system.
02:09
Now net force on the block plus incline is always zero.
02:19
Here the answer is also not zero.
02:23
The net force acting on the block and incline is not zero...
