Two electrostatic point charges of +60.0 uC and +50.c uC exert a repulsive force on each other of 175 N. What is the distance between the two charges?

• Physics -

Solve
F = k Q1 * Q2/R^2

You know everything but R. Look up the value of k

• Physics -

d^2=(k*Q1*Q2)/F

d^2=(8.99*10^9)(60*10^-6uC)(50*10^-6uC)/175
d^2=0.154
square root of d^2= square root of 0.154
d=0.392m or 3.92cm
