Equation reads as follows:

L1=c.g.-32=___-32, L1=___cms

calculate L2= m1/m2 (L1)=____ ( ); L2=____cms

experimental L2= x-c.g. when stick is balanced

L2=_____-______; L2= _____ cms

(experimental)

Percentage error= larger-smaller/calculated value x 100

Percentage error= ( )-( )/( ) x 100

Percentage error=_________%

I put 13.5 on the first blank and -18.5 on the second. On the m1/m2 blank, I put 32/81 (-18.5) ; L2= -7.31 On the experimental L2= 81-45.5=35.5. Please let me know if I am doing this correctly. I don't know even where to begin with the percentage error. Can you please help????????????
