The state nickname for the state of Minnesota is the "North Star State." because it is the English translation and most frequently used translation for the official French L’Etoile Du Nord that appears on other Minnesota state emblems — the seal and the state flag. Minnesota is the only U.S. state to have a motto in French. While the reason for this is not clearly known, most historians speculate that the choice of the French language is a deferential nod to the early French explorers, missionaries and traders who settled the wilds of Minnesota before the region became a territory and a U.S. state. The "North Star State" motto refers to Minnesota as the northernmost state in the United States.
And Minnesota sits north of all the contiguous U.S. states, its right border extending toward the Great Lake Superior. Native American tribes populated the land until the arrival of traders and missionaries from France and explorers from England in the 1600s. After the American War for Independence, a portion of the territory was incorporated into the United States of America. Minnesota became the 32nd state to join the United States in 1858.

Minnesota is known as the "North Star State" because its state motto, "L'Étoile du Nord," translates to "The North Star" in English. This nickname celebrates the state's northern location in the U.S. and its French heritage from early explorers. Additionally, the North Star, or Polaris, has been a significant navigational point in the northern sky.

Jawaban:Diketahui: - Muatan 1 (Q₁) = -9 μC = -9 x 10⁻⁶ C- Muatan 2 (Q₂) = -4 μC = -4 x 10⁻⁶ C- Jarak antara muatan (r) = 10 cm = 0,1 m a. Letak Titik dengan Kuat Medan Listrik Nol - Konsep: Kuat medan listrik di suatu titik adalah nol jika medan listrik yang dihasilkan oleh kedua muatan saling meniadakan. Karena kedua muatan negatif, titik ini harus berada di antara kedua muatan.- Langkah-langkah:1. Tetapkan Variabel: Misalkan titik tersebut berjarak x dari Q₁ dan (0,1 - x) dari Q₂.2. Rumus Kuat Medan Listrik: Kuat medan listrik (E) oleh sebuah muatan titik adalah E = kQ/r², di mana k adalah konstanta Coulomb (8,99 x 10⁹ Nm²/C²).3. Persamaan: Kita ingin E₁ = E₂, sehingga:- k |Q₁| / x² = k |Q₂| / (0,1 - x)²- |Q₁| / x² = |Q₂| / (0,1 - x)²4. Substitusi Nilai:- (9 x 10⁻⁶) / x² = (4 x 10⁻⁶) / (0,1 - x)²- 9 / x² = 4 / (0,1 - x)²5. Sederhanakan:- Ambil akar kuadrat dari kedua sisi: 3/x = 2/(0,1 - x)- 3(0,1 - x) = 2x- 0,3 - 3x = 2x- 0,3 = 5x- x = 0,06 m = 6 cm- Jawaban: Titik dengan kuat medan listrik nol terletak 6 cm dari muatan -9 μC dan 4 cm dari muatan -4 μC. b. Potensial Listrik di Titik Tersebut - Konsep: Potensial listrik di suatu titik adalah jumlah potensial listrik yang dihasilkan oleh semua muatan di sekitarnya. Potensial listrik (V) oleh sebuah muatan titik adalah V = kQ/r.- Langkah-langkah:1. Hitung Potensial oleh Q₁:- V₁ = kQ₁ / x = (8,99 x 10⁹ Nm²/C²) * (-9 x 10⁻⁶ C) / (0,06 m)- V₁ = -1348500 V = -1,3485 x 10⁶ V2. Hitung Potensial oleh Q₂:- V₂ = kQ₂ / (0,1 - x) = (8,99 x 10⁹ Nm²/C²) * (-4 x 10⁻⁶ C) / (0,04 m)- V₂ = -899000 V = -0,899 x 10⁶ V3. Hitung Potensial Total:- V_total = V₁ + V₂ = -1,3485 x 10⁶ V + (-0,899 x 10⁶ V)- V_total = -2,2475 x 10⁶ V- Jawaban: Potensial listrik di titik tersebut adalah -2,2475 x 10⁶ V atau -2,2475 MV.
