A massive ball is suspended on a string and slowly pulled by another string attached to it from below, as shown in Figure A below
a. Is the string tension greater in the upper or the lower string? which string is more likely to break? which property, mass or weight, is important here?
b. If the string is instead snapped downward, which string is more likely to break? is mass or weight important this time?
A. Upper string because it supports the weight of the ball in addition to your pull. The lower string supports only your pull. The upper string is more likely to break. Weight is important here.
B. bottom string; the mass of the ball(its inertia) is more important then its weight in this case.
