yg bisa jawab nomor 1 smpe 5 pake cara sya ksih jwbn terbaik dan nilainya lumayan byk....

1.) Tolak menolak jika muatannya sejenis. Tarik menarik jika muatannya tidak sejenis

2.) q₁ = 25 mC = 2,5 x 10⁻² C
q₂ = -8 mC = -8 x 10⁻³ C
k = 9 x 10⁹ Nm²/C²
r = 30 cm = 3 x 10⁻¹ m
F = _?

F = k • q₁ • q₂ / r²
= 9 x 10⁹ • 2,5 x 10⁻² • 8 x 10⁻³ / (3 x 10⁻¹)²
= 20 x 10⁶ N
= 2 x 10⁷ N

3.) q₁ = 5 C =
q₂ = 12 C
k = 9 x 10⁹ Nm²/C²
F = 2,16 x 10¹² N

r = _ ?

F = k • q₁ • q₂ / r²
2,16 x 10¹² = 9 x 10⁹ • 5 • 12 / r²
r² = 25 / 10²
r = 5 / 10
r = ½ m

4.) Q = 80 C
r = 10 m
k = 9 x 10⁹ Nm²/C²

E = _?

E = kQ / r²
= 9 x 10⁹ • 80 / 10²
= 7,2 x 10⁹ N/C

5.) Q = 5 x 10⁻⁵ C
r = 20 cm = 2 x 10⁻¹ m
k = 9 x 10⁹ Nm²/C²

E = _?

E = kQ / r²
= 9 x 10⁹ • 5 x 10⁻⁵ / (2 x 10⁻¹)²
= 11,25 x 10⁶ N/C
= 1,125 x 10⁷ N/C
