Serhud [2]

Complete question:

The left plate of a parallel plate capacitor carries a positive charge Q, and the right plate carries a negative charge -Q. The magnitude of the electric field between the plates is 100 kV/m. The plates each have an area of 2 x 10⁻³ m², and the spacing between the plates is 6 x 10⁻³ m. There is no dielectric between the plates. What is the charge on the capacitor?

Answer:

The charge on the capacitor is 1.77nC

Explanation:

Given;

magnitude of electric field between the plates, E = 100 kV/m

Area of each plate, A = 2 x 10⁻³ m²

Distance between the plates, d = 6 x 10⁻³ m

Charge on the capacitor is calculated as;

Q = CV

V = Ed

C = \epsilon_o \frac{A}{d}

Q = CV =  \epsilon_o \frac{A}{d}*Ed\\\\ Q =  \epsilon_o AE\\\\Q = 8.85*10^{-12} *2*10^{-3}* 100,000\\\\Q = 1.77 *10^{-9} \ C\\Q = 1.77 \ nC

Therefore, the charge on the capacitor is 1.77nC

The pilot of an airplane flying at an elevation of 5000 feet sights two trees that are 300 feet apart. If the angle of depressio
OLEGan [10]

Answer:

32°

Explanation:

From the diagrammatic representation of the question,

Point A is the pilot point of view from the airplane

Point C is the foot of the first tree

Point D is the foot of the second tree

Line AB is the height of the airplane from the ground level.

Line CD is the distance between the two trees

Considering ΔABC,

tan 33° = \frac{5000}{BC}

BC = 5000 / tan 33°

BC = \frac{5000}{0.6494}

BC = 7,699.41 feet

BD = BC + CD

BD = 7,699.41 + 300

BD = 7,999.41 feet

Considering ΔABD,

tan θ = \frac{AB}{BD}

tan θ = \frac{5000}{7,999.41}

tan θ = 0.6250

θ = tan⁻¹ 0.6250

θ = 32°
