<span>Radius, the distance from the centre = 0.390
Electric field is equal to half of the magnitude. E2 = E / 2
Given
E1 = E2
E1 = k x Q / r^2
E2 = (k x Q / r2^2) / 2
Equating the both we get 2 x r^2 = r2^2
r2 = square root of (2 x r1^2) = square root of (2) x r = 1.414 x 0.390
r2 = 1.414 x 0.390 = 0.551 m</span>
A large amount of molten magnetic material containing Iron is believed to rotate (as a liquid) in the Earth’s core.
The forces of gravity between two objects depend on the masses
of both objects. So if one mass increases, then the objects will be
drawn together by stronger gravitational force.
Example:
When a person eats a lot of steak and fat and carbohydrates, his
mass increases, and the bathroom scale shows that the gravitational
forces drawing him and the Earth together have increased. We say
that he has "gained weight".
