draw the electric field lines between two negatively charged particles. according to coulomb's law, how would the electrical force between these particles change if they were moved farther apart?

Explanation :

The region around a charge in which an electrostatic force is experienced is called electric field. It is also defined as an electrostatic force per unit electric charge.

Electric field lines are the imaginary lines to represent the electric field. The field lines always start form positively charged particle and terminate at the negatively charged particle.

For a positive charge, field lines are outwards while for a negative charge field lines are inwards.

For a system of two negatively charged particles, the electric field lines are shown in the attached figure.

According to Coulomb's law, the electrostatic force between two charged particle is given by :

where,

r is the distance between two charges. The electrostatic force is inversely proportional to the square of the distance.

So, if the charged particles are moved farther apart, the electrical force would decrease.

sorry idk the answer well to you i have a explaination

explanation: a formula which shows the arrangement of atoms in the molecule of a compound

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g
