Hi guys, let's start this question.
00:04
So in the question it is given that there is a block of mass 2kg and it rests on an inclined plane.
00:11
So let's draw the diagram.
00:13
So here we have an inclined plane and here we have a mass.
00:19
The value of this mass is m.
00:21
The value of the m is actually 2kg.
00:27
Now here the angle is theta and this theta is actually 30 degrees.
00:34
Now after that the coefficient of friction is the amount.
00:36
Mu so from here the value of mu is actually 0 .7 what will be the frictional force acting on the block now we have to calculate the value of the frictional force acting on the block so for that firstly draw all the forces on this block now there is a force m g in the downward direction there will be a normal reaction forced by the inclined plane and there will be a force of friction by this surface like this.
01:13
Now after that, let's decide the x and the y axis.
01:16
So this is going to be our x -axis and this is going to be our y -axis...
