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
Therefore, the charge on the capacitor is 1.77nC
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°
BC = 5000 / tan 33°
BC = 7,699.41 feet
BD = BC + CD
BD = 7,699.41 + 300
BD = 7,999.41 feet
Considering ΔABD,
tan θ
tan θ
tan θ = 0.6250
θ = tan⁻¹ 0.6250
θ = 32°
