Answer:
Width of the slit will be equal to 1.47 mm
Explanation:
We have given wavelength of the light
Distance D = 8 m
Distance between first minimum dark fringe and the central maximum is 2 mm
So
We have to find the width of the slit
For the first order wavelength is equal to , here a width of slit
So
So width of the slit will be equal to 1.47 mm
Answer:
The distance is
Explanation:
From the question we are told that
The coefficient of static friction is
The initial speed of the train is
For the crate not to slide the friction force must be equal to the force acting on the train i.e
The negative sign shows that the two forces are acting in opposite direction
