sir i have asked this question previously also ….sir can we take component of normal reaction…so then
Ncos theta=mg (acting downwards)
but u have taken mgcos theta = N
sir also there is no acceleration of the block
sir why my way of doing this question is wrong
For simple calculation, we take the component of that force which is not perpendicular or parallel to acceleration.
If we see that normal force which is perpendicular to acceleration.
