Question 1178647: The formula F=Kq1q2/r^2 gives the force between two point charges of q1 and q2 coulombs that are r metres apart. If two equally charged balls are placed 0.1m apart and the force between the balls is 9.8*10^-4 Newtons, calculate the charge on each ball to 2 significant figures, given K=9.0*10^9.

The formula F=Kq1q2/r^2 gives the force between two point charges of q1 and q2 coulombs that are r metres apart. If two equally charged balls are placed 0.1m apart and the force between the balls is 9.8*10^-4 Newtons, calculate the charge on each ball to 2 significant figures, given K=9.0*10^9.

r= 0.1
F= 9.8*10^-4 Newtons,
K=9.0*10^9.
q=?

q=
