Calculate the force between two objects that have masses of 70 kilograms and 2000 kilograms separated by a distance of 1 meter

Judging by the kind of information you gave, I'm guessing that
you're looking for the gravitational forces drawing these two
objects together.

Gravitational force:                 F = G  m₁ m₂ / R²

F = gravitational force, newtons
G = gravitational constant = 6.67 x 10⁻¹¹ newton-meter²/kg²
m₁ = mass of one object, kg
m₂ = mass of the other object, kg
R = distance between their centers, meters

Using the data given in the question . . .

      F = (6.67 x 10⁻¹¹ N-m²/kg²) (70 kg) (2000 kg) / (1 m)²

         = (6.67 x 10⁻¹¹  x  70  x  2000)  Newton

         =    9.338 x 10⁻⁶  Newton

           (about 0.000034 ounce)

Julia would be observing a. static electricity was caused by her sweater rubbing against her shirt and transferring electrons. she didn't touch anything metal, so that would cancel out b.she most likely didn't rub her sweater against her hair either, so that cancels out c.she also didn't scoot across the carpet while trying to take her sweater off, that cancels out d.so that leaves a.a. is correct.
