Question

me harian esta tarea porfa?

Answer 1

Explicación:

1.

q1 = 2c ; q2 = 3c

r = 2000m

k = 9×10⁹ N×m²/c²

$f = \frac{9x10 {}^{9} \times 2 \times 3}{(2000) {}^{2} }$

$f = \frac{437,566.53208907}{4000000}$

$f = 0.109391633 = 0.11n$

las fuerzas se repelen al ser ambas positivas.

2.

q1 = 9c ; q2 = 5c

F = 2×10⁷ N

$2x10 {}^{7} = \frac{9x10 {}^{9} \times 9 \times 5}{r {}^{2} }$

$r {}^{2} = \frac{9x10 {}^{9} \times 45 }{2x10 {}^{7} }$

$r {}^{2} = \frac{3,281,748.990668}{2x10 {}^{7} }$

$r {}^{2} = 1,799,437,380.4028$

$r = \sqrt{1,799,437,380.4028} =$

$r = 42,419.775817451 = 42.420m$

3.

son fuerzas de repulsión.

4.

q1 = ? ; q2 = 8c

r = 8m

F = 7×10⁹N

$7x10 {}^{9} = \frac{9x10 {}^{9} \times q1 \times8 }{(8) {}^{2} }$

$q1 = \frac{7x10 {}^{9} \times64 }{9x10 {}^{9} \times 8}$

$q1 = \frac{3,630,181.5995537}{583,422.04278542}$

$q1 = 6.2222222222 = 6.2c$
