RUMUS KUAT MEDAN LISTRIK
 |
| Rumus kuat medan listrik |
PENJELASAN :
E = Kuat medan listrik ( n/c )
F = Gaya listrik
q = Muatan
K = Konstanta ( 9.109 nm/c2 )
Q = Muatan listrik ( c )
r2 = Jarak ( m )

CONTOH SOAL
Rc = 8 cm =
0,8 m 8/100 = m 8.10-2
Rc = 10 cm
= 0,1 m 100/100 m =1/10 = 1- 10-1 m
Ra = 12 cm =0,12
m 12/100 m = 12.10-2 m
k = 9.1o5 n2 /c2
JAWAB: EC = O rc < R
EA = K-Q =
0.3125.10-9 N/C
(RA)2
= 9.109 -5.10-4
EB = k.q
(12-10-2) (rb)2
= 45.105-4
144.10-4
