Electric Field Strength E = Force F/ Charge q
E = F/q
Force , F = E*q
But charge on an electron q = 1.6 * 10⁻¹⁹ C
E = 3 * 10³ N/C from the question.
Force F = 3* 10³ * 1.6 * 10⁻¹⁹
F = 4.8 * 10⁻¹⁶ N.
Electrostatic force F = 4.8 * 10⁻¹⁶ N

Answer:
50 N
Explanation:
Let the natural length of the spring = L
so
100 = k(40 - L) (1)
200 = k(60 - L) (2)
(2)/(1): 2 = (60 - L)/(40 - L)
60 - L = 2(40 - L)
60 - L = 80 - 2L
2L - L = 80 - 60
L = 20
Sub it into (1):
100 = k(40 - 20) = 20k
k = 100/20 = 5 N/in
Now
X = k(30 - L) = 5(30 - 20) = 50 N
To find the radial velocity of the object we are going to apply the regular Doppler formula:
[measured wavelenght - rest wavelenght/ rest wavelenght] = V/C, where V is the radial velocity and C is the speed of light which is equal to 300,000km/sec.
[400 - 800/800] = V/300,000 = - 150,000.
This means that the object is moving at a velocity of 150,000km/sec toward the observer.
The minus sign infront of the answer indicates that the object is moving towards the observer while a positive value will indicate that the object is moving away from the observer.
<u>Answer;</u>
weak interaction
<h3><u>Explanation;</u></h3>
- The weak force is one of the four fundamental forces that govern all matter in the universe (the other three are gravity, electromagnetism and the strong force).
- <u><em>Weak interaction is the mechanism of interaction between subatomic particles that causes radioactive decay and thus plays an essential role in nuclear fission. Only weak interactions can cause the decay of fundamental particles.</em></u>
