We can feel it as heat, using the nerve endings in our skins.
Answer:
The required radial distance from the center of the toroid is -
<u>r = 4.34 cm</u>
Explanation:
We know that magnetic field inside a solenoid is given by -
B = μni
where 'μ' is the magnetic permeability , 'n' is the number of turns per unit length , 'i' is the current passing through solenoid.
given n = 550 turns/meter
We know that magnetic field inside a toroid is -
B = μ××i [Current is same in both the devices] , where 'N' is the total number of turns in the toroid and 'r' is the radial distance from the center of the toroid.
Given N = 150.
Equating the two magnetic fields , we get -
μni = μ××i
∴
Substituting the values we get -
r = 0.0434 m = 4.34 cm
To solve this problem we will apply the definitions given in Newtonian theory about the Force of gravity, and the Force caused by weight. Both will be defined below, and in equal equilibrium condition to clear the variable concerning acceleration due to gravity. Finally, with the values provided in the statement, it will be replaced.
The equation for the gravitational force between the Earth and the object on the surface of the Earth is
Where,
G = Universal gravitational constant
= Mass of Earth
= Distance between object and center of earth
= Mass of Object
The equation for the gravitational pulling force on the object due to gravitational acceleration is
Equation the two expression we have
This the acceleration due to gravity which is composite constant.
Replacing with our values we have then
The value of composite constant is . Here, the composite constant is nothing but the acceleration due to gravity which is constant always.
They are held together because of Strong Nuclear Force.
