benda a dan b masing-masing bermuatan listrik -100 micro columb dan + 125 micro columb berjarak 25 cm.besar gaya tarik menarikkedua muatan tsb bila k=9.10^9 nmkuadrat/ckuadrat adalah..??
E = 400N/C
Q=?
V = E x R
600 = 400 R
R = 600/400 = 1,5 m
V = k Q/R
VxR/k = Q
600x1,5/ 9 x10^9 = Q
10^-7 C = Q
jd besar muatannya 1x 10^-7 C
