Answer:
mgL(1 - cosθ)
Explanation:
At angle θ, the vertical distance from the mass m to the pivotal axle is Lcosθ. While at U=0, this distance is L. Due to the mass is hanging straight down. Therefore the vertical distance from this lowest point to point at angle θ is
L - Lcosθ
The change in potential energy would be this height difference times mg
where g is the gravitational constant
Answer:
The distance between the slits is given by 1.3 × m
Given:
D = 4 m
y =
m = 1
To find:
distance between slits, d = ?
Formula used:
y =
y = distance of first bright band from central maxima
D = distance between screen and source
d = distance between slits
= wavelength
Solution:
distance of first bright band from central maxima is given by,
y =
y = distance of first bright band from central maxima
D = distance between screen and source
d = distance between slits
= wavelength
Thus,
d =
d =
d = 1.28 ×
d = 1.3 × m
The distance between the slits is given by 1.3 × m
