Hi, I solved this problem, but I want to make sure it is correct:
2 equal charges are separated by 3.7x10^10m. The force between the charges has magnitude of 2.37x10^3N.What is the magnitude of q on the charges?
F= ( k x q x q)/ (r^2)
F=2.37 c 10^3 N
k= 9 x 10^9
r= 3.7 x 10^10
q= 3.64 x 10^16 << answer<<<
Is this correct? Please let me know asap!

bobpursley,
q=sqrt[(2.37E3)(3.7E10)^2 /(9e9)]
Paste this into your google search window
sqrt((2.37E3)(3.7E10)^2 /(9e9))
