Particles q1, q2, and q3 are in a straight line. Particles q1 = -5.00 x 10-6C, q2 = +2.50 x 10-6C, and q3 = -2.50 x 10-6C. Particles q1 and q2 are separated by 0.500m. Particles q2 and q3 are separated by 0.250m. What is the net force on q2? Remember: Negative forces (-F) will point left, Positive forces (+F) will point right.

Will award brainliest to the correct answer. Thanks!

Pls pls pls pls ! describe, in your own words, how you found the epicenter of the earthquake.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
