Aphysicist conducts two experiments:
experiment 1:
initially, two objects, each equal to the charge and mass of one electron, are spaced one meter apart; the electric and gravitational forces are measured. then, the charge and mass of each object is increased by the charge and mass of one electron; again, the electric and gravitational forces are measured. the experiment continues adding mass and charge in the same increments until the objects have the masses and charges equivalent to 10 electrons.
experiment 2:
initially, two objects, each equal to the charge and mass of one electron, are spaced one meter apart; the electric and gravitational forces are measured. then, the objects are moved 1 meter farther apart; again, the electric and gravitational forces are measured. the experiment continues increasing the distance in one-meter increments until the objects are 10 meters apart.
how will the gravitational and electric forces between the objects change in each experiment?
a
in experiment 1, the gravitational and electric forces will increase as the square of the charge and mass increase. in experiment 2, the gravitational and electric forces will decrease as the square of the distance increases.
b
in experiment 1, the gravitational and electric forces will increase as the square of the charge and mass increase. in experiment 2, the gravitational and electric forces will decrease linearly as the distance increases.
c
in experiment 1, the gravitational and electric forces will increase linearly as the charge and mass increase. in experiment 2, the gravitational and electric forces will decrease as the square of the distance increases.
d
in experiment 1, the gravitational and electric forces will increase linearly as the charge and mass increase. in experiment 2, the gravitational and electric forces will decrease linearly as the distance increases.
