It appears that the nominal values are all 10000U, but the initial margins are different: one is 1000U, and the other is 2000U.
One is 10x, and the other is 5x.
If we ignore any fees, then ideally: the former goes bankrupt to zero when the price fluctuates by 10%, while the latter goes bankrupt when the price fluctuates by 20%.
In reality, there will be many intermediate losses involved: assuming the fee rate is 0.1%, then 10U will be deducted as a fee.
So we can roughly consider that the margins are only 990U and 1990U. (In reality, the calculations are more complex than this.)
At this time, the nominal values are 9900U and 9950U.
If there is a recent unilateral trend, the current mainstream perpetual contracts, funding rates are also a factor. Assuming three times a day for a total of 0.15%, holding for 10 days may result in funding losses of 49.5U and 49.75U respectively.
This loss will likely result in a reduction of 0.5% in price fluctuations leading to liquidation.
In reality, due to the rapid changes in market prices, platforms will not actually wait for the price to reach your liquidation price to trigger liquidation (this differs from what most people understand). In other words, the margin ratio will not directly reach 0 before liquidation; instead, a so-called maintenance margin rate is defined, usually around 0.5%, which will also affect the final liquidation.
Roughly calculated, these two items together affect 1%.
Therefore, the final price fluctuations may cause one to go bankrupt at about 9%, while the other will only go bankrupt at 19%.
