This is either a trick question or a very hard one. In the first case: An electric field cannot occur inside a conductor (or by using the superposition principle you find out that at this point your electric fields cancel each other out)... Or you must use the laplace equation and proper boundary conditions to solve for the electrostatic potential

Answer:
brainly getting too strict smh...
Explanation:
Answer: 24.7 degrees Max
Explanation:
m*g = 3 * 9.8 = 29.4 N. = Wt. of book.
Fp = 29.4*sin A = Force parallel to the
plank.
Fn = 29.4*Cos A = Force perpendicular to
the plank.
Fs = u*Fn = 0.46*29.4*Cos A
Fp-Fs = m*a
29.4*sin A - 0.46*29.4*Cos A = m*0 = 0
29.4*Sin A = 0.46*29.4*Cos A
Sin A = 0.46*Cos A
Divide both sides by Cos A:
Sin A/Cos A = 0.46
Replace Sin A/Cos A with Tan A:
Tan A = 0.46
A = 24.7 degrees Max.
Answer:
Explanation:
The figure of the problem is included below as attachment. The equations of equilibrium are presented below:
The system of equations are:
![N_{1} \cdot [(0.75\,m)-0.2\cdot (0.35\,m)] - N_{2}\cdot (1.25\,m) = 0](https://tex.z-dn.net/?f=N_%7B1%7D%20%5Ccdot%20%5B%280.75%5C%2Cm%29-0.2%5Ccdot%20%280.35%5C%2Cm%29%5D%20-%20N_%7B2%7D%5Ccdot%20%281.25%5C%2Cm%29%20%3D%200)
The solution of the system is:
, 
and 
The shortest time to reach a speed of 80 km/h is:
