If friction is acting along the plane upwards
then in this case we will have
For equilibrium of 100 kg box on inclined plane we have

also for other side of hanging mass we have

now we have




In other case we can assume that friction will act along the plane downwards
so now in that case we will have

also we have

now we have





<em>So the range of angle will be 23.45 degree to 37 degree</em>
Answer:
Explanation:
Given that :
The current I = 8.6 A
The length vector L = 2.3 m i
The force vector is = -2.0 j N
When L = 2.3 m i ; the
Force vector F = (2.0 i - 4.8 k) N
Compute the components of the magnetic field as follows:

Replacing 8.6 A for I ; -2.0 j N for F & 2.3 m i for L



However in y direction ; we have :



Hence, the component of magnetic field is as follows:

Bro again the same type of sum..
well
it takes 3 second to hit the ground
the height will be
h = 5*3*3
h = 45m
horizontal distance would be
velocity*time
10*3 ,= 30m/s
