My answer was 2.39E3 since it had to be converted to micro coulombs. However, the answer was wrong.

Can someone please help me with this problem? I have only one trial left to answer for this problem..

Here , Below is the way I solved but the answer was wrong.

as E = -dV/dx

E = d/dx(5 *10^12 * x^2)

E = 1 *10^13 *x N/C

Now, let the charge inside the cube is q

(1 * 10^13* 0.03 * 0.03^2) = q/8.854 *10^-12

q = 2.39 *10^-3 C

the charge is 2.39 *10^3 uC

    Can someone tell me where I'm going wrong? I have these two problems: The professor uploaded a video explaining how to solve them (generally, he didn't use numbers. He said the steps are the same for both problems except for the last step since the first problem is asking for magnitude and the second is asking for an angle. I followed his steps but I keep getting the wrong answer.) Also for the 2nd question I'm not sure if I'm...
