How far apart should two protons be if the electrical force of repulsion on each one is equal to its weight on the earth? ( k = 1/4πε 0 = 9.0 × 10 9 N ∙ m 2/C 2, e = 1.6 × 10 -19 C, m proton = 1.67 × 10 -27 kg)

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.

the answer would be c

i think the answer is tomato juice? not entirely sure though
