Question

For the answer, select all that apply for seesaw problem below.

Consider the two blocks on the seesaw below. The wedge is fixed at the center of the seesaw. If the larger box has twice the mass as the smaller, what are two possible ways that the seesaw could be balanced (select all that apply)? The distance measured from the center of the seesaw where the wedge is located is r. Note: For the larger box, r = r large and for the smaller box, r = r small A. r small = 2 r large B. r small = 4 r large C. r small = (1/2) r large D. r small = (1/4) r large E. r large = 2 r small F. r large = 4 r small G. r large = (1/2) r small H. r large = (1/4) r small

Explanation / Answer

see saw can be balanced if the torque due to larger mass and smaller mass balance each other
T of larger mass = T of smaller mass
2m*g*rlarge = m*g*rsmall
2*rlarge = rsmall

so answers are:
r small = 2* rlarge
r large = (1/2)* r small
That is options A and G
