Which image below represents the electric field lines between two positively charged particles? (2 points)
Group of answer choices
A positive particle sits in the center of a dotted circle. There is a negative particle along the dotted circle.
Two particles sit side by side. There are curved field lines that point from one particle to the other in a counter clockwise direction above the particles and a clockwise direction below the particles.
Two particles sit side by side. There are curved field lines that point away from each particle. The particle on the right has field lines pointing to the right. The particle on the left has field lines pointing to the left.
One particle sits in the center of curved field lines that extend beyond the particle then return to the particle. Arrows along the curved field lines point in a clockwise direction above the particle and a counter clockwise direction below the particle.

The ultracentrifuge is an important tool for separating and analyzing proteins. because of the enormous centripetal accelerations, the centrifuge must be carefully balanced, with each sample matched by a sample of identical mass on the opposite side. any difference in the masses of opposing samples creates a net force on the shaft of the rotor, potentially leading to a catastrophic failure of the apparatus. suppose a scientist makes a slight error in sample preparation and one sample has a mass 10 mg larger than the opposing sample. if the samples are 12 cm from the axis of the rotor and the ultracentrifuge spins at 70,000 rpm, what is the magnitude of the net force on the rotor due to the unbalanced samples? ( be thorough on your answer)
