I used NSolve as follows:
NSolve[{t == el/v, eE q - m g == m a, y == (1/2) a t^2}, {q, a, t}]

I input the following parameters:
m=1.5e-10
eE=1.2e6
el=10e-3
v=20
y=1.3e-3
g=9.8

I get the following result:
{{q -> 0., a -> 10400., t -> 0.0005}}

I should get q = 1.3e-12

Why does NSolve not give me the correct value for q?

thanks, Brett
