Answer: 4.5 x 10^-36 N
Explanation: The interaction between the charges is not electrical because the distance ( between the protons) is too large.
The interaction is gravitational because one is placed on earth and the other on the moon.
The force of repulsion between these two protons can be gotten using newton's law of gravitational force which is mathematically given below as
F=(G*m1*m2)/r²
F = Gravitational force
G = gravitational constant =6.674 x 10^-11
m1 = mass of the first proton =1g=0.001kg
m2 = mass of second proton =1g=0.001kg
r = distance between the earth and the moon = 3.844 x 10^9m
Slotting the parameters into the formula, we have that
F= 6.674x10^-11 x 0.001 x 0.001/(3.844 x 10^9)²
F= 6.694 x 10^-17/ 14.77 x 10^18
Finally
F = 4.5 x 10^-36N
Answer:
Therefore
Number of turns in the solenoid is 19407.
Explanation:
Given:
Strength magnetic field at its center,
B = 7.5 T
length of solenoid = l = 0.26 m
Current, I = 80 A
To Find:
Turn = N = ?
Solution:
If N is the number of turns in the length, the total current through the rectangle is NI. Therefore, Ampere’s law applied to this path gives
Therefore,
Where,
B = Strength of magnetic field
l = Length of solenoid
N = Number of turns
I = Current
Substituting the values we get
Therefore
Number of turns in the solenoid is 19407.
