A fixed system of charges exerts a force of magnitude 22 N on a 4.0 C charge. The 4.0 C charge is replaced with a 8.0 C charge.
1 answer:
Answer:
44 N
Explanation:
The electrostatic forces between two charges is given by:
where
k is the Coulomb's constant
q1 and q2 are the two charges
r is their separation
We notice that the force is directly proportional to the charges.
In this problem, initially we have a force of
F = 22 N
on a q2 = 4.0 C, exerted by a charge q1.
If the charge is doubled,
q2 = 8.0 C
This means that the force will also double, so it will be

Explanation:
The wave with the least amount of wavelength will have the greatest amount of energy.
Wavelength and energy shares an inverse relationship;
E = h f =
From this equation, we see that the higher the energy of a wave, the lesser its wavelength.
- Choice A from the options has the least wavelength.
- Wavelength is the distance between two successive crests of a wave.
This is why we see that in the electromagnetic spectrum, radio waves have the least energy because they have the longest wavelength.
Answer:
Explanation:
The torque applied by a force can be calculated as
where
F is the magnitude of the force
d is the length of the arm
is the angle between the direction of the force and the arm
In this problem, we have
F = 15 N
d = 2.0 m
Substituting into the equation, we find
