Answer:
1000 N
Explanation:
The magnitude of the electrostatic force between two charged object is given by
where
k is the Coulomb constant
q1, q2 is the magnitude of the two charges
r is the distance between the two objects
Moreover, the force is:
- Attractive if the two forces have opposite sign
- Repulsive if the two forces have same sign
In this problem:
are the two charges
r = 3000 m is their separation
Therefore, the electric force between the charges is:
The energy of a single photon at the transmitted frequency is
Answer: Option b
<u>Solution:</u>
Energy of photon is given as
Where c is the velocity of Light
h is planck's constant
λ is the wavelength of photon
Energy of photon can be rewritten as
Where f is the frequency of photon
Frequency of photon is obtained by dividing velocity of light by wavelength of photon.
