Answer:
Y = 5.03 x 10⁻³ m = 5.03 mm
Explanation:
Using Young's Double-slit formula:
where,
Y = Fringe Spacing = Width of bright fringe = ?
λ = wavelength = 633 nm = 6.33 x 10⁻⁷ m
L = Screen distance = 3.1 m
d = slit width = 0.39 mm = 3.9 x 10⁻⁴ m
Therefore,
<u>Y = 5.03 x 10⁻³ m = 5.03 mm</u>
Answer:
Explanation:
Net external force that exerted on the block is given as
here we know that
now we have
so we have
now the force exerted by bigger block on smaller block is given as
now we know that two blocks will exert equal and opposite force on each other
so here the force exerted by 2 kg block on 4 kg block will be
