We have that the force between the two charged objects is mathematically given as
F=2.349N
<h3>Magnitude of the force between two charged objects.</h3>Question Parameters:
Two spheres carry a charge of 1x10^-7 C.
Their centers are <u>separated</u> by 0.7m.
Generally the equation for the Force is mathematically given as
Therefore
F=2.349N

Answer:
The magnetic field in the center of the solenoid is .
Explanation:
Given that,
Length of solenoid = 0.425 m
Number of turns N = 950
Current I = 2.75 A
The magnetic field in the center of the solenoid is the product of the current , number of turns per unit length and permeability.
In mathematical form,
Where,
N = number of turns
L = length
I = current
Now, The magnetic field
Put the value into the formula
Hence, The magnetic field in the center of the solenoid is .
When plane is flying along the wind then we can say
Now when its going against the wind the speed is given by
Now by the above two equations we will have
