Untuk atom hidrogen pada orbit Bohr n = 2, tentukan gaya listrik yang berkerja pada elektron! 

  1. ... begin mathsize 14px style blank to the power of blank end style

  2. ... begin mathsize 14px style blank to the power of blank end style

Jawaban:

begin mathsize 14px style e equals 4 comma 803 cross times 10 to the power of negative 10 end exponent space gr to the power of bevelled 1 half end exponent cm to the power of bevelled 3 over 2 end exponent straight s to the power of negative 1 end exponent m subscript e equals 9 comma 1 cross times 10 to the power of negative 28 end exponent space gr h equals 6 comma 626 cross times 10 to the power of negative 27 end exponent space gr space cm squared space straight s to the power of negative 2 end exponent end style  

begin mathsize 14px style n equals 2 end style

Ditanya: begin mathsize 14px style F subscript e equals... end style F subscript c

F subscript c equals k e squared over r subscript n squared space space space space space equals 9 x 10 to the power of 9 left parenthesis 1 comma 6 x 10 to the power of 19 right parenthesis squared over left parenthesis 2 comma 12 x 10 to the power of negative 10 end exponent right parenthesis squared space space space space equals 5 comma 13 x 10 to the power of negative 9 end exponent N

Jadi, gaya listrik yang berkerja pada elektron adalah begin mathsize 14px style 5 comma 13 cross times 10 to the power of negative 9 end exponent space straight N end style
