The table lists pressure and volume values for a particular gas. Which is the best estimate for the value of V at P = 7.0 × 103 pascals?
P (pascals) V (liters)
5.0 × 103 6.0
1.5 × 104 3.0
2.0 × 104 2.0
2.5 × 104 1.5

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
