Answer: The force does not change.
Explanation:
The force between two charges q₁ and q₂ is:
F = k*(q₁*q₂)/r^2
where:
k is a constant.
r is the distance between the charges.
Now, if we increase the charge of each particle two times, then the new charges will be: 2*q₁ and 2*q₂.
If we also increase the distance between the charges two times, the new distance will be 2*r
Then the new force between them is:
F = k*(2*q₁*2*q₂)/(2*r)^2 = k*(4*q₁*q₂)/(4*r^2) = (4/4)*k*(q₁*q₂)/r^2 = k*(q₁*q₂)/r^2
This is exactly the same as we had at the beginning, then we can conclude that if we increase each of the charges two times and the distance between the charges two times, the force between the charges does not change.
Answer:
= 1220 nm
= 1.22 μm
Explanation:
given data:
wavelength 
distance of screen from slits D = 3 m
1st order bright fringe is 4.84 mm
condition for 1 st bright is
---( 1)
and
= 0.0924 degrees
plug theta value in equation 1 we get
condition for 1 st dark fringe
= 2λ since from eq (1)
= 1220 nm
= 1.22 μm
Answer:
The given statement is correct.
When the light becomes brighter then the electron emitted per second increases.
when light is incident on the metal it delivers energy in the form of small energy packets.
these small energy packets is known as photons.
More the intensity of light more the photon will be emitted.
Electron gain kinetic energy after absorbing energy from the photon.
