e. begin mathsize 14px style OC space colon space CA end style 

Jawaban:

Diketahui O C equals 10 j with rightwards arrow on top space dan space O A equals negative 2 j with rightwards arrow on top

table attributes columnalign right center left columnspacing 0px end attributes row cell C A end cell equals cell O A minus O C end cell row blank equals cell negative 2 j with rightwards arrow on top minus 10 j with rightwards arrow on top end cell row blank equals cell negative 12 j with rightwards arrow on top end cell end table

Jadi perbandingan

table attributes columnalign right center left columnspacing 0px end attributes row cell OC space colon space CA space end cell equals cell 10 j with rightwards arrow on top space colon space minus 12 j with rightwards arrow on top end cell row blank equals cell 5 space colon space minus 6 end cell end table
