Answer:

Explanation:
According to Coulomb's law, the magnitude of the force (F) between two objects with the same charge(+Q), separated a distance (d) apart, is defined as:

Here k is the Coulomb constant. The charge on each object is doubled, that is
:

Answer: The correct answer is- Field.
Explanation -
The modified space around a charged particle is known as electric field.
The strength of electric field at a point is calculated as the force experienced by a unit test charge present at that point.
Thus, a region of space in which a test charge experiences a force is referred to as Field.
Answer:
7
Explanation:
A substance that is neither acidic nor basic is neutral. The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral.
Next to oceans due to high specific heat of sea water.
