Strange as it may seem, it takes 1836 electrons to make the mass of ONE proton or neutron.
So if you have one proton AND one neutron in a jar, there's enough mass in there to make 3672 electrons.
That's choice-D .
Position of B :
x = 4.66*cos 30 = 4.036
y = 3-4.66*sin 30 = 3-2.33 = 0.67
BC = √y^2+(x-1)^2 = √0.67^2+3.036^2 = 3.109
heading = arctan y/(x-1) = arctan 0.67/(3.036) = 12.44° south of west
hope this helps :)

Answer:
1/r
Explanation:
The magnetic field produced by a current in a wire decreases with distance from the wire, this means the magnetic field produced by a currents is inversely proportional to it's distance from the wire.
Let E be magnetic field and r distance of wire
We have that,
E is inversely proportional to r
(E)×(1/r)
