Work
q1= 8.75*10^-6 C
q2=-6.5*10^-6 C
r=.025 m
so Force=(8.988*10^9) X (q1*q2)/r^2 = 8.1*10^-4 N (q1*q2) is absolute value
but where do i go from here?
point charges in an electric field
Homework Statement
Problem: A +8.75 micro C point charge is glued to a frictionless table. It is tied to -6.5 micro C point charge by a 2.5 cm string (weightless and nonconducting). A uniform electric field of magnitude 1.85*10^8 N/C is directed parallel to...
