Two positively charged particles are 0.03 m apart. The first particle has a charge of 8.1 C, and the second a charge of 2.6 C. Which change would lead to the smallest increase in the electric force between the two particles? A. Decrease the charge on each particle by 1.0 C. B. Decrease the charge on the first particle by 1.0 C. C. Increase the charge on the first particle by 3.0 C. D. Increase the charge on each particle by 2.0 C.

for me it was Double the charge on the second particle.

Explanation:

C

Explanation:

just did it :)

current flows in a wire

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
