Answer:
1/9 of that just outside the smaller sphere
Explanation:
The electric field strength produced by a charged sphere outside the sphere itself is equal to that produced by a single point charge:

where
k is the Coulomb's constant
Q is the charge on the sphere
r is the distance from the centre of the sphere
Calling R the radius of the first sphere, the electric field just outide the surface of the first sphere is

The second sphere has a radius which is 3 times that of the smaller sphere:

So, the electric field just outside the second sphere is

So, the correct answer is 1/9.
Answer:Extreme pressure from burial, increasing temperature at depth, and a lot of time, can alter any rock type to form a metamorphic rock. If the newly formed metamorphic rock continues to heat, it can eventually melt and become molten (magma). When the molten rock cools it forms an igneous rock.

Answer:
i know the questin but i got to try and find it
Explanation:
Answer:
That is false, Protons have a positive charge, Electrons have a negative charge, and Neutrons have a blank charge.
