Answer:

Explanation:

The application of Gauss's law is used in the derivation as shown with detailed step by step in the attached file.

The potential difference on this spherical capacitor is ΔV = Va - Vb = kQ/a - kQ/b = kQ(1/a - 1/b)

padilas [110]

Answer:

The percentage of the weight supported by the front wheel is  A= 19.82 %

Explanation:

B] Let the mass of plane be m, force on backwheels be Nb and nosewheel be Nn

Torque equation about nose wheel,

mg*(2.58-0.8) - Nb *(3.02-0.8) = 0

Nb =  mg*(2.58-0.8)/(3.02-0.8) = 0.8018 mg

Nn = mg - Nb = (1-0.8018) mg = 0.1982mg

Weight percentage supported by front wheel = 19.82% answer
