Particles q1, 92, and q3 are in a straight line. Particles q1 = -28.1 uc, q2 = +25.5 uc, and
q3 = -47.9 MC. Particles qi and q2 are separated
by 0.300 m. Particles q2 and q3 are separated by
0.300 m. What is the net force on q3?
Remember: Negative forces (-F) will point Left
Positive forces (+F) will point Right

we need some answer choices, or something like that

explanation:

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
