I'm was trying to solve for the electrostatic force given that the object was stationary and that m= 5 grams.
I realize now that mgtanθ=FE, but according to this quick picture I made, Fgy=FT, so (mgcosθ)(sinθ)=FE, but that's not right.
I was wondering if I did something wrong, or if doing it that way just doesn't work.
homework goes to >>>/hm/
mg/tanθ

I think this is not right.

GTFO with your high school kiddie shit, read the sticky
>>7947968
But there is no explanation as to why mgcosθsinθ doesn't work.
Nigga you got components that aren't parallel. Do you even know what a fucking axis is?

The tick marks indicate equal forces, not paralleliness.
[eqn]
\begin{aligned}
\int \frac{\cos(\sqrt{x})}{\sqrt{x}} \; dx &= \int 2\cos{u} \; du \quad \quad u = x^{\frac{1}{2}} \; \; 2du = \frac{1}{\sqrt{x}} \, dx \\
&= 2 \sin{u}+C \\
&= 2 \sin{\sqrt{x}}+C
\end{aligned}

If you set up y-axis like that then you have to include the y component of Fe

wrong
