Question

Tolong bantu, kelas 10, terima kasih.​

Answer 1

Jawaban:

1.

k = 9x10⁹ Nm²/C²

q1 = 8000 μC = 8000  x10⁻⁶ C

q2 = -500  μC = -500 x10⁻⁶ C

r = 30 cm = 0,3 m

F = ?

F = k q1 q2 / r²

F = 9x10⁹ x 8000  x10⁻⁶ x 500 x10⁻⁶ / 0,3²

F = 4x10⁵ N

2.

k = 9x10⁹ Nm²/C²

q = 70000 μC = 70000  x10⁻⁶ C

r = cm = 0,03 m

E = ?

E = k q/r²

E = 9x10⁹ x 70000  x10⁻⁶/0,03²

E = 7x10¹¹ N/C
