The distance measured from the center of the seesaw where the wedge is located is r. Note: For the larger box, rlarge and for the smaller box, r small O A. rsmall 2 large B. rsmall-4 rlarge c. rsmall = (1/2) range D. rsmall = (1/4narge OE. narge 2 Tsmall O G. rlarge = ( 1 /2) rs mall 0 H. rlarge = ( 1 /4) rsmall
