Answer:
Explanation:
Given:
- un-stretched length of the spring,
- speed of revolution of the ball in horizontal plane,
- length stretch during the motion,
<u>Now the radius of revolution of the ball:</u>
<u>Now in this case the centrifugal force is equal to the spring force:</u>
where:
m = mass of the ball
k = spring constant
<u>Now the extension in the spring upon hanging the ball motionless:</u>
Answer:
width of slit =1.23× 10⁻⁶ m
Explanation:
we know the condition of diffraction minima,
d sin θ = n λ
λ = wavelength θ = angle between the central maxima and 1st minima
d = slit width
for first minima n = 1
now,
d =
d =
d = 1228 × 10⁻⁹ m = 1.228× 10⁻⁶ m
d = 1.23× 10⁻⁶ m
width of slit =1.23× 10⁻⁶ m
