Question

Two particles are separated by 0.38 m and have charges of -6.25x 10-9 C
and 2.91 x 10-9 C. Use Coulomb's law to predict the force between the
particles if the distance is cut in half. The equation for Coulomb's law is
Fe=
kag, and the constant, &, equals 9.00 x 10º N-m?/C2

A. -1.13 x 10-6 N

B. 4.53 x 10-6 N

C. 1.13 x 10-6 N

D. -4.53 x 10-6 N

Answer 1

Answer: -4.53×10-6N

Explanation:

The magnitude of the electrostatic force F between two point charges q1 and q2 is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them. Like charges repel each other, and opposite charges mutually attract.
