force on two particles??
A charge q1 =4uC is at the origin, and a charge q2 = 6.0uC is on the x-axis at x = 5m. In what follows, i denotes the unit vector in +x direction.
i know how to do this problem, just plug into equation and go. but i keep getting the wrong answer. i will show what I am doing and hopefully someone will see my mistake. might be something wrong with my constant or my conversion factor.
this problem uses the whole F= k * ((q1q2)/r^2)
q1 = 4uC i converted to C to get 4 x 10 ^ -6 C
q2 = 6uC converted to C to get 6 x 10 ^ -6 C
r = 5
k = 1.3807 x 10 ^ -23
just plug and chug
1.3807 x 10 ^ -23 * 4 x 10 ^ -6 * 6 x 10 ^ -6 = 3.314 x 10 ^ -34
divide by r^2 (25) = 1.325 e -35
that is not right. should be a normal number not to a power
any help would be great
thanks
