(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A small charge of -2 micro-colombs which has a mass of 0.5 kg lies on level ground. A charge of +5 micro-colombs is a distance of 0.35 meters above the charge. What is the magnitude of the normal force in Newtons on the -2 micro-colomb charge? Do not ignore gravity for this problem.

2. Relevant equations

F_e_=k[(q1q2)/r^2] F_m_=mg

3. The attempt at a solution

F_e_=0.7339 N and F_m_=4.9N

Can anyone tell me if I'm going in the right direction with this problem?
